The pop-up says
Could not run the 'C:\Program Files\Microsoft Visual Studio .NET 2003\VC#\CSharpProjectItems\LocalProjectItems\..\CSharpAddClassWiz.vsz' wizard.
Annoying. You can't create a new project, can't create a new class. Nothing.
Cause ? Some Add-in messed up all the wizards or scripting or both.
Been working on this since 10 am today and no success. Google says this is a popular search, and Microsoft hasn't posted a fix. Doomsday. So I tried what Pete here suggested.
1: Open a command prompt and go to the IDE directory of your VS.NET install. On my machine it's found here: C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\IDE
2: Type: regasm extensibility.dll
3: Type: regasm vslangproj.dll
4: Download this file (regtlb.zip) and unzip it to a location that's in your path. I have a utils directory where I keep a bunch of command prompt tools.
5: Go to the directory: C:\Program Files\Common Files\Microsoft Shared\MSEnv
6: Type: regtlb vslangproj.tlb
Still no relief from the constant whining and popups. What do we do next? Reinstall Microsoft Scripting Engine from this page.
Oops, its asked me restart my machine. Be back and write down what happened.
Back
Worked. Phew.
Back to coding.
