DLL Compatibility Checker for Windows 7

Hi guys,

Our company needs an application that tells if our custom software's DLL is compatible with Windows 7. I tried MS Application Compatibility Toolkit but unfortunately it doesn't tell nor determine if DLL is compatible in Windows 7.

If I'm going to create a program just to check if DLLs are good in Windows 7 64bit, what do I need to know? Say I'm going to use VB.net or Java, what are the namespace or classes that I'll be needing. The Custom DLL Checker program-to-be will be ran in Windows XP.

The result would be just saying "myCommon.DLL is not compatible with Windows 7 64 bit"

Many thanks in advance.

What is a "custom software's DLL?" Are you talking about a custom DLL you wrote? If not, what makes a DLL "belong to" some "custom software?"

Setting that aside...

No, there is no magical set of attributes you might simply interrogate. Compatibility involves thousands of issues from things like old APIs that might be gone to security changes to directory structure changes to screen rendering changes.

A lot depends on whether your code followed the rules. E.g. not hard-coding special folder paths, not writing to things in protected directories or registry keys, properly testing for OS version, writing for Standard User use, etc.

And 64-bit issues are separate from Windows 7 issues.
