The contents of that folder should not be removed, evidently it has. A safer
detour is to find the actual original MSI file that was used to install your
Visual Studio and copy it into the installer folder with that name. That
oddly-named MSI file is a cached version of the original (without the files)
so you can substitute the original MSI file there.

Who? Not me for sure. :-)

Given the link I posted, I was able to make a clean deinstall (I used the
vs_bla.msi from the orignal CD).
Unfortunatelly, the deinstallation created a new problem: There was the
folder "%CommonProgramFiles%\Microsoft Shared\vs7debug". As the name says,
it was there for VS*7*, that means VS 2003. Now, whenever I start a project
in the VB *2005* IDE, I get an error complaining about a missing msdbg2.dll
in just that VS7Debug folder.
Why does VB 2005 need a DLL from VS 2003?
The error message also suggests to do a repair install. I will try this and
hope it will solve the problem, though I'm still interested in the answer to
the question above.
More info: I saved the VS7debug folder before uninstall. When I examine the
msdbg2.dll, it shows description "Microsoft Visual Studio 7.0 Debugging
Proxy/Stub" but file version is 8.0.50727.42. Versions don't fit together,
IMO. There seem to be other VS8 files in the VS7Debug folder - why /there/?

I can't really comment on the manual method of removing VS since it's not my
field at all, just the MSI stuff.
I believe there are some common Dlls between 2003 and 2005, IIRC related to
opening a .sln file and picking the right IDE, 2003 or 2005.

Thanks Phil, and sorry for answering that late, but my newsreader usually
shows the group red if there's a new message in my thread but it didn't this
time, thus the late answer.
Though, I think a "vs7debug" folder shouldn't be used from VS8 at all.
