When I tried to go into a video call on msn messenger with my Microsoft LifeCam VX-1000, it would throw an error something to the effect of "messenger is not available".

In order to fix it, I changed the compatibility setting in the properties for Windows Live Messenger (right click properties on Start -> All Programs -> Windows Live -> Windows Live Messenger) to "Windows XP (Service Pack 3)".

The usual way:

    C:\>gacutil.exe /u[f] <assembly name>

If it can't find gacutil.exe, check the %windir%\Microsoft.NET\Framework\v1.1.4322\ directory.

In this command, assembly name is the name of the assembly to uninstall from the GAC. The following example removes an assembly named hello.dll from the GAC.

    gacutil /u "hello,Version=1.0.0.0, Culture=neutral, PublicKeyToken=0123456789ABCDEF"

If you still can't uninstall it, here's a solution from Peter Huang [MSFT] that should work. The original post is at: http://bytes.com/topic/net/answers/49299-uninstall-assembly-gac#post366811

1. Run cmd in run dialog.
2. cd %systemroot%\assembly\gac\ClassLibrary1\1.0.1322.2 1592__22df95e3b227e638
(My test dll is ClassLibrary1.dll)
3. del ClassLibrary1.dll
4. del __AssemblyInfo__.ini
5. cd..
6. rd 1.0.1322.21592__22df95e3b227e638
7. cd..
8. rd ClassLibrary1

You may perform the steps above to see if the ClassLibray1 has been removed from the GAC.

Here's an online manual for WinRAR:

The blog is in part an archive of sorts for all the solutions I found for all the programming (or other) issues I have run into.

Whenever I run into a problem, I go off and Google the solution but the solution isn't always reachable that easily. Like everyone, I sometimes wade through the post of one person's issue which is sort of related to my problem to get to a comment of a person who gives a link to a solution for something that's closer to what I'm experiencing AND then check out the comments on that post to maybe use that solution or discover my own from all the information

Please remember that the majority of solutions will be snippits from other pages and/or links to the original page and are not my own; whenever possible the original link is included. Hopefully you might find some solution here for something that's been boggling you and I encourage you to visit the original links for the complete articles and their comments. You never know, it could be the one link that solves your issue
