Installation Instructions

Installing Adobe Acrobat Reader 5.0 for Macintosh

To install Acrobat Reader 5.0, follow these steps:

-Make sure you have at least 24 MB of available disk space for an installation of Acrobat 5.0 Reader.

-Double-click on the Acrobat 5.0 Reader installer and follow the steps to install Acrobat Reader.

Installing the PDFViewer plug-in for multiple copies of Netscape or Internet Explorer

When you install Acrobat Reader 5.0, if multiple copies of Netscape or Internet Explorer are found on your Macintosh, you are prompted to select which one will receive the PDFViewer plug-in that enables the viewing of PDF files within the browser. If you later use a copy of Netscape or Internet Explorer which does not have the PDFViewer installed into it, you will not be able to view PDF files in that browser. The workaround is to copy the PDFViewer plug-in from your Acrobat Reader 5.0 folder into your default Netscape or Internet Explorer plug-in folders.

Adobe SVG Viewer 2.0

Adobe Acrobat Reader 5.0 installs Adobe SVG Viewer 2.0. To learn more about Adobe SVG Viewer 2.0 use your browser to open the ReadMeSVGViewer.html file located within your browser's plugins folder.

Installing Asian Language Files for Acrobat Reader 5.0

Asian Language Files are available for Acrobat Reader 5.0. With any language version of Acrobat Reader 5.0, you can display Adobe Portable Document Format (PDF) files that contain text in Chinese Simplified, Chinese Traditional, Japanese, and Korean (CJK). All you need to do is install the appropriate Asian font pack for use with Acrobat Reader. To install Asian Language support launch the Acrobat Reader installer, select Custom Install and select the Asian Language files option.

Asian Language Files will only install to one Acrobat Reader Folder
If you have more than one copy of Acrobat Reader on your system the Asian Language Files will only install fonts into a single Acrobat Reader folder. You may manually copy the installed fonts which are located in Adobe Acrobat (Reader) 5.0 / Resource/ CIDFont. [289100]

Troubleshooting Issues

Using Acrobat 4.x or Acrobat Reader 4.x to view and print files created in Acrobat 5.0
You can use Acrobat 4.x or Acrobat Reader 4.x to view and print PDF files created with Acrobat 5.0, taking note of the following:
-PDF files with 128-bit encryption will not open in Acrobat 4.x,
-Transparency is not supported in Acrobat 4.0; PDF files containing such graphics can only be fully appreciated in Acrobat 5.0,
-Scanned PDF files which use JBIG2 compression will not open in Acrobat 4.x,
-Acrobat 5 enables any font on your system to be used in a Free Text annotation. However, Acrobat 4.x allowed only the base PostScript Roman fonts and the Heisei Japanese fonts. If a Japanese Free Text annotation is created in Acrobat 5.0 using fonts other than the Japanese Heisei fonts, this text annotation will not be displayed correctly on Acrobat 4.x, [397619]
-PDF files that contain new JavaScript operators may issue errors to the JavaScript console if run in Acrobat 4.0.
-PDF files whose fonts use new predefined CMaps may not open properly in Acrobat 4.0
-Some forms created in Acrobat 5.0 may generate FDF data that cannot be parsed correctly by server-side CGI scripts written with the Acrobat 4.0 FDF Toolkit
-Acrobat Form fields in Acrobat 4.x supported only a limited number of fonts. While the forms tool in Acrobat 5.0 enables you to specify any font in a form field, Acrobat 4.x may not display such a form correctly.[397754, 312623,410665]

Select the Auto-Configure Browser preference to view PDF files in the browser
When this preference is checked (Edit > Preferences > Options > Web Browser Options > Auto-Configure Browser), Acrobat Reader 5.0 will check to see that all MIME types are correctly established in the Internet Configuration database and in Netscape preferences.
Also, Acrobat Reader 5.0 will scan all installed browsers to verify that a current version of the PDFViewer plug-in has been installed. See the section entitled "Installing the PDFViewer plug-in for multiple copies of Netscape" for more details. [414484]

Using the Toolbar
Acrobat Reader's toolbars can be torn-off, docked on the top, and their geometry may be changed. Torn-off toolbars cannot be combined by dragging the title bar of the toolbar; use the drag handle of the toolbar instead.[398112]

Viewing PDF files within Internet Explorer and Netscape
When attempting to view relatively large PDF files, you may see an error message saying "Page processing error. File input/output error. Time out during connecting." Other symptoms that you may see are Acrobat Reader displays blank pages or Acrobat Reader may hang. Check with your systems or network administrator that the version of Apache being used is 1.3.17 or greater. Acrobat Reader may exhibit the symptoms listed above with earlier versions of Apache.[417553]

Acrobat Reader Web-Based Features on Mac OS 8.6
When Acrobat Reader 5.0 launches you may see this message: "Features that require internet access have been disabled due to operating system limitations. Please see the ReadMe file for more detail."
Acrobat Reader 5.0 features that require internet access are disabled on Mac OS 8.6 due to operating system limitations. The following features require an operating system library called URL Access:
- Application features delivered via remote services such as Create PDF Online and Search Adobe PDF Online are disabled and do not appear
-Update Acrobat and Update Web Services are not available - when you select Edit > Preferences > General > Update and then select Update Acrobat Now and Update Web Services Now, you see the message: "Acrobat cannot check for updates because it is missing plug-ins required to search for updates." Acrobat cannot load these plug-ins because URL Access is not available.[417483]
- Notification of product and service updates - while updates of your system through Acrobat Reader 5.0 are not available, you can download any available updates of your software by checking http://www.adobe.com/acrobat/ periodically.

Adobe Systems is not able to install this library on MacOS 8.6 as it has in the past. Currently Apple Computer Inc only supports it on MacOS 9.0 and above. [411146]

Chinese, Korean, and Japanese (CJK) Acrobat Substitution Fonts
Attempting to activate by Adobe Type Manager and use the Acrobat CJK substitution fonts that are installed by Acrobat (for example, KozMinPro-Regular-Acro.otf) is not recommended and results may be unpredictable.[390851]

CJK Text Display in Acrobat Reader Dialogs
On a Roman system, Chinese, Korean, and Japanese (CJK) text cannot be displayed in Acrobat Reader dialogs. Acrobat Reader requires a CJK system with the appropriate CJK system font in order to display CJK characters in its dialogs.[395326]

CJK Text Display when Overprint Preview is on
When a PDF containing CJK characters that have a relatively complicated glyph design, is viewed with Overprint Preview turned on, the text may look less clear than when Overprint Preview is turned off.[416395]

CJK Forms
On a system which does not have Asian Language Support installed, if you open a CJK Forms PDF which contains differently encoded CJK characters than those the Form was created with, the CJK Form fields will be displayed as dots. To prevent this, be sure to install Asian Language Support on systems that will be viewing and using CJK Forms. See this ReadMe's section titled "Installing Asian Language Files for Acrobat Reader 5.0" above for additional information. [412829]

Extract Images Preference
In the Acrobat Help section titled "Setting Acrobat Preferences", the Extract Images preference is defined incorrectly. The Help states the preference "Defines the minimum size an image must be to display on screen". The Extract Image preference actually defines to Acrobat the minimum size an image must be in order for Acrobat to extract it from a PDF. [417231]

Find Dialog - Using Find to Locate Unicode Characters
You can use Find to locate Unicode characters within a PDF document. To do this, add a "\u" in front of the Unicode character for which you want to search. For example, to search for the Unicode equivalent of the ASCII character "A", enter "\u0041" in the Find dialog. For some CJK characters, such as Unicode "4e01", you can specify "\u4e01".[413632]

Function Keys
If function keys do not work within Acrobat Reader (for example, F1 does not open Acrobat Reader Help) your function key settings may be turned off. Turn them on by: clicking the check box found at: Apple menu > Control Panel > Keyboard > Function Keys... > Function Key Settings.[405350]

Helvetica and Times Fonts
Acrobat Reader 5.0 will now use Helvetica and Times Fonts on PDF files that do not have these files embedded. Acrobat Reader 4.0 required the user to place these fonts into the Acrobat Reader 4 folder and also required you to remove the ArialMT and or TimesNewRomanPSMT fonts from the Acrobat fonts folder before Times and Helvetica would be used.

The following conditions must be met for Acrobat Reader to use Adobe Type 1 Times and Helvetica fonts when a pdf file is encountered that does not have these fonts embedded (the most common case):
-The latest Adobe Type 1 Helvetica and TimesRoman fonts must be on your system. They must contain Euro, ZCaron & zcaron glyph, as do the latest versions available in Adobe Type basics.
-You must have Adobe ATM installed. If you don't, you may place these fonts in Acrobat Reader's Font folder which is in the Resource folder.
-If you are using Adobe ATM, there must be no other older copies of these Type 1 fonts available on your system, on any disk drive. If the older versions exist and ATM is aware of them, Acrobat Reader will substitute the standard ArialMT and TimesNewRomanPSMT fonts instead.[303849]

Acrobat 5 support for the Hong Kong Supplemental Character Set
The Hong Kong Special Administrative Region Government recently introduced the Hong Kong Supplemental Character Set (HKSCS). Acrobat 5 allows you to view and print PDF files containing HKSCS characters on the Macintosh operating systems supported by Acrobat 5.0 (see the System Requirements section). If you would like to view or print PDF files that contain text using the Hong Kong character set, please install support for the Chinese Traditional character set using Custom Install, or installing the Chinese Traditional Language Files.[418559]

Hong Kong Character Set and Comments and Bookmarks
Acrobat Reader 5.0 supports the Hong Kong character set for text in a PDF file. It is an extension to the Adobe Chinese Traditional character set. If you would like to view or print PDF files that contain text using the Hong Kong character set, please install support for the Chinese Traditional character set using Custom Install, or installing the Chinese Traditional Language Files. Since the Hong Kong character set is not part of the standard system fonts you will not be able to comment or create bookmarks using Hong Kong characters.[407877]

MacOS X and Acrobat 5.0 Reader
Although Adobe has tested Acrobat Reader 5.0 on pre-release versions of MacOS X, Acrobat Reader 5.0 is not certified to run on MacOS X as final testing was not completed at the time Acrobat Reader 5.0 shipped. [413033, 413674]

Movie Plug-in - viewing a movie in a floating window
When viewing a movie that plays in a floating window, you can stop the movie at any time by pressing the Escape key. In addition, when viewing a PDF file in a web browser that includes a QuickTime VR movie, that movie will not play correctly unless it is set to play in a floating window.[410153]

Movie Plug-in - MPEG 2 video attachments
MPEG 2 video attachments may not play correctly within Acrobat Reader 5.0. [283674]

Movie Plug-in - Remote URL requires QuickTime 4 or later
If you will be using the Movie tool to view Movies by pressing a link to a remote link, be sure to have QuickTime 4 or later installed on your system. [418201]

Netscape 4
Avoid pressing the Back button while PDFViewer is reloading. Pressing the Back button within Netscape 4 while PDFViewer is reloading may cause an unexpected exit in Netscape 4 requiring you to restart Acrobat. To prevent this, wait until the PDFViewer completes reloading before pressing the Back button.[415737]

Netscape 6
Acrobat Reader installs a plug-in to work with Netscape 4.x browsers. This plug-in enables users to download, view, navigate and print Adobe PDF files, and to fill in PDF forms while working inside the browser. With Netscape 6, PDF files must be downloaded in their entirety before they can be viewed. Also, with Netscape 6, PDF forms cannot be filled in when viewed within the Browser. To print a PDF file from Netscape 6 use the print icon on the Acrobat Reader toolbar from within Netscape instead of File>Print.

Printer Specific Options
Due to a bug in CarbonLib (version CarbonLib 1.2.5 or before) if you use AdobePS as a printer driver and set options in the print dialog box (such as Layout-Pages per Sheet, or Paper Handling) these settings do not affect the printed output. The workaround is to use LaserWriter as a printer driver or to Save Setting, to commit the options and then print.[405522]

Printing ImageType 4 files to Lexmark printers
Image Type 4 is a feature of PostScript 3. While application software creates ImageType 4 files somewhat infrequently, a PDF created from a GIF file with transparency using Acrobat WebCapture will contain ImageType 4.
When files containing ImageType 4 are printed to the Lexmark printers listed below, the printer may hang and no output is produced. The Lexmark printer models are:
-Lexmark Optra C710 PS3, PS Version 3010.010, PS revision 2000411
-Lexmark Optra W810PS3, PS Version 3010.010, PS revision 990917

To work around this problem, you have two options:
1. Choose Print As Image from the Print dialog. This will produce results similar to what you see on the screen.
2. If your platform is Windows, you can change the Print Method from Language Level 3 to Language Level 2. However, on the Macintosh, there is no Print Method field. To get the same effect, you could edit the PPD file to make it reflect language level 2, for example, change:
*PSVersion: "(3010.010)"
to:
*PSVersion: "(2014.700)"
Do not change your PPD file if Print As Image produces the desired results. Forcing the file to print at language level 2 enables Image Type 4 to print, but all transparency will be lost.[416539]

Reflow
Documents cannot be reflowed at certain magnification and window width combinations. Acrobat Reader magnifies the document to whatever magnification level it can display without failing. [401685]

Save A Copy
Acrobat Reader 5.0 contains a menu item and a toolbar icon called "Save A Copy". If you modify an Adobe PDF file in Acrobat Reader 5.0, your changes will not be preserved when you use this command. Only a copy of the original Adobe PDF file will be saved; saving updates is not a feature of Acrobat Reader.[414048]

Search
Search is not available within Acrobat Reader 5.0 on Mac OS X.

Temporary Files
There is a bug in MacOS 9.0.x in which Temporary Items are not deleted at Startup. This is corrected in MacOS 9.1. There is a description of the problem, and a workaround described in AppleCare Tech Info Library, case #25134. You can view this at:
