Microsoft Windows operating system versions 3.1, 3.11

SUMMARY

This article describes how reconfigure your Windows 3.11 installation to run Windows 3.10 using your original Windows 3.10 disks. If you do not have these disks available, contact Microsoft Product Support Services (PSS) and order Application Note WW1007, "Installing Windows 3.10 Files over Windows 3.11."

MORE INFORMATION

To install Windows 3.10 files over a local installation of Windows 3.11:

Quit Microsoft Windows.
Create a backup directory. For example, to create a backup directory off the root of drive C, type "md c:\backup" (without the quotation marks) at the MS-DOS command prompt and then press ENTER.
Copy the files listed below from your Windows SYSTEM subdirectory to the backup directory or a floppy disk.
```
      COMMDLG.DLL

      GDI.EXE

      KRNL386.EXE

      PSCRIPT.DRV

      SHELL.DLL

      UNIDRV.DLL

      USER.EXE
```
To do this, use the following syntax
```
      copy <drive>:\<windir>\system\<filename> <drive>:\<backdir>
```
where <drive> is your hard disk drive, <windir> is your Windows directory, <filename> is the file you are copying, and <backdir> is your backup directory.

For example, if your hard disk drive is C, your Windows directory is named WINDOWS, you are copying COMMDLG.DLL, and your backup directory is named C:\BACKUP, type the following:
```
      copy c:\windows\system\commdlg.dll c:\backup
```
Repeat this command for the remaining files.
Using the table at the end of this article, insert the appropriate disks, one by one, and expand the following files to your Windows SYSTEM subdirectory.
```
      COMMDLG.DL_

      GDI.EX_

      KRNL386.EX_

      PSCRIPT.DR_

      UNIDRV.DL_

      SHELL.DL_

      USER.EX_
```
For example, insert Disk 4 of the 3.5 inch, 1.44-megabyte (MB) disk set and type the following at the MS-DOS command prompt:
```
      expand a:\commdlg.dl_ c:\windows\system\commdlg.dll
```
PSCRIPT.DR_ should be expanded to PSCRIPT.DRV, .DL_ files should be expanded to .DLL, and .EX_ files should be expanded to .EXE.

NOTE: After you copy the new USER.EXE file to your Windows SYSTEM subdirectory, your registered user and company name will be blank.
If you use Novell NetWare connectivity, do the following:
a. Use a text editor (such as Windows Notepad) to open your
```
      SYSTEM.INI file, which is located in your Windows directory.
```
b. In the [386Enh] section, change DEVICE=VTDA.386 to DEVICE=*VTD.

c. Save the file and quit the text editor.

To install Windows 3.10 files over a network installation of Windows 3.11:

Determine the location of your SYSTEM.INI file and the network share that contains your shared Windows files. For example, if the network drive containing your Windows program files is Q, the location of your shared Windows files may be Q:\WINSHARE and your user directory may be Q:\USER\YOURNAME (or your user directory may be located on your local hard disk drive).
Quit Microsoft Windows.
Create a backup directory. For example, to create a backup directory off the root of drive C, type MD C:\BACKUP at the MS-DOS command prompt and then press ENTER.
Copy the following files from the network share to the backup directory on your hard disk drive using the following syntax at the MS-DOS command prompt and then press ENTER.
```
      copy <netdrive>:\<netshare>\<filename> <harddrive>:\<backdir>
```
where <netdrive> is the network drive, <netshare> is the network share containing your SYSTEM.INI file, <filename> is the file you are copying, <harddrive> is your hard disk drive, and <backdir> is your backup directory.

For example, if your network drive is Q, the network share is WINSHARE, the file you want to copy is COMMDLG.DLL, your hard disk drive is C, and your backup directory is named C:\BACKUP, type the following:
```
      copy q:\winshare\commdlg.dll c:\backup
```
Repeat this command for the remaining files:
```
      COMMDLG.DLL

      GDI.EXE

      KRNL386.EXE

      PSCRIPT.DRV

      UNIDRV.DLL

      SHELL.DLL

      USER.EXE
```
Remove the read-only file attributes on the shared Windows files using the MS-DOS ATTRIB command.
Using the table at the end of this article, insert the appropriate disks, one by one, and expand the following files to the network drive and share that contains your Windows files:
```
      COMMDLG.DL_

      GDI.EX_

      KRNL386.EX_

      PSCRIPT.DR_

      UNIDRV.DL_

      SHELL.DL_

      USER.EX_
```
For example, insert Disk 4 of the 5.25-inch, 1.2-MB disk set and type the following at the MS-DOS command prompt:
```
      expand a:\commdlg.dl_ q:\winshare\commdlg.dll
```
PSCRIPT.DR_ should be expanded to PSCRIPT.DRV, .DL_ files should be expanded to .DLL, and .EX_ files should be expanded to .EXE.

NOTE: After you copy the new USER.EXE file to your Windows SYSTEM subdirectory, your registered user and company name will be blank.
Reset the read-only file attributes on the shared Windows files using the MS-DOS ATTRIB command.
If you use Novell NetWare connectivity, do the following:
a. Use a text editor (such as Windows Notepad) to open your SYSTEM.INI
```
      file.
```
b. In the [386Enh] section, change DEVICE=VTDA.386 to DEVICE=*VTD.

c. Save the file and quit the text editor.
