Microsoft INTERIX 2.2 Subsystem Update for Softway INTERIX 2.2 SP1

Microsoft Corp. acquired Softway Systems Inc., September 16, 1999, and is transitioning the product line. Microsoft is committed to Interix technology. Watch for more information on Interix in the coming months.

The first Microsoft release of INTERIX is Microsoft INTERIX 2.2. This is essentially the Softway Systems INTERIX 2.2 SP1 product. The primary difference between the Softway and Microsoft editions of the product are that the Microsoft edition runs on Windows 2000.

The cabinet file MSIX22_1.CAB contains a subsystem (POSIX.EXE, PSXSS.EXE, PSXDLL.DLL, PSXRUN.EXE) that is ready for Windows 2000. Customers of Softway Systems INTERIX 2.2 SP1 can lay down this cabinet file and INTERIX will run on Windows 2000. The original Softway Systems product keys will continue to work and you can now use INTERIX 2.2 on Windows 2000.

The rest of this "Read Me" file contains:

The Packing List for the Cab file.
How to determine if you have a correct version of INTERIX to use this Cabinet file.
Extracting and Installing the cabinet file.

Packing List

POSIX.EXE
PSXDLL.DLL
PSXRUN.EXE
PSXSS.EXE
READ1ST.TXT—This file.
MSINTERIX22.TXT—The Read First file that ships with MS INTERIX 2.2
LICENSE.TXT—The MS INTERIX 2.2 End User License Agreement

How to Determine if you can Use this Cabinet File

In the Windows NT Explorer or from My Computer locate the INTERIX subsystem, PSXSS.EXE, in %Windir%\system32 and look at the version information in the file properties (File->Properties; Version tab).

If the subsystem version is 2.2.428.0 or greater, then it is already Windows 2000 enabled.

If the subsystem version is 2.2.202 or lower, then Softway INTERIX 2.2 SP1 was NEVER installed or the historical Softway patchs NEVER applied. The current Cabinet file may cause a number of problems and should NOT be installed. Please purchase Microsoft INTERIX 2.2 to run on Windows 2000.

Extracting and Installing the Cabinet File

Ensure the following:

Ensure there are no INTERIX based services set to run automatically on reboot.
Ensure INTERIX subsystem (PSXSS.EXE) is not running. A reboot (after Step 1 above is the best way.)
Ensure you are running as Administrator.
From a CMD.EXE command line, unpack the cab file with expand or extract as follows: 7 files total. 
>extract /e MSIX22_1.CAB /l \temp /y
