When opening a newly installed program the following error occurs.

The Microsoft Jet database engine cannot open the file C:\Widows32\Win2sys.dll It is already opened exclusively by another user, or you need permission to view its data.

It works fine in Windows XP but not in Windows 7.

Does the file Win2sys.dll exist? If it does, can you see what company made it? i'm pretty sure it's not something that ships with Windows. – Ian Boyd Mar 2 '10 at 19:20

win2sys.dll is a Trojan.Dropper-BS. win2sys.dll spreads via open network shares. Related files: %Windows%\csrss.exe %Windows%\win2sys.dll More info: http://www.sophos.com/virusinfo/analyses...

Troj/Dropper-BS is a dropper Trojan for the Windows platform.

When Troj/Dropper-BS is installed the following files are created:

\csrss.exe

\win2sys.dll

The file csrss.exe is detected as Troj/LdPnch-V.

The following registry entry is created to run code exported by the Trojan library on startup:

Just open the file location of that application: Right click » Properties » Compatibility. Just change the compatibility to "Windows XP". That's it. That application will run without any error.
