Recurring UNIDRV.DLL Version 3.1

When I install a program(Win95) the current UNIDRV.DLL(Win95) is replaced by the older version(3.1) and I can't seem to find where that file is taken from.  And everytime I have to manually recopy the Win95 version.  Have any idea on how to fix this problem?

If your UNIDRV.dll has a date of 7/11/95, it probably is a
16bit for Windows 3.x
Check your build number. It maybe coming from C:\WINDOWS\SYSBCKUP. Are you getting and Error message.
Extract Unidrv.dll from your CD-ROM like this:
Finding Windows 95 Files
Finding a Single File:
You can use the Extract tool to determine which cabinet file contains a particular Windows 95 file. When you use this syntax, the Extract tool searches the cabinet files but does not extract the file once it is found:

EXTRACT /A /D <cabinet> <filename>

For example, to find the UNIDRV.DLL file, starting with the
WIN95_02.CAB file, using disks in the x drive "X is your CD drive", use the following


Once extracted, put it your Windows\system directory and get rid of all others.
