Hello to all,

I'm having a problem in installing Visual Studio 6 on a machine running
Windows XP SP2. Whenever the installation reaches the end, I get the message
"pdm.dll was unable to register itself in the system registry", followed by a
message stating that the installation has failed. I am then able to run
Visual Studio, but cannot uninstall it and also cannot apply service packs. I
also have Visual Studio 2005 installed, but the problem seems to have
occurred even before I installed 2005.

There is a limited number of results when I perform a search on this issue,
and one of them suggests renaming the existing pdm.dll files and trying
again. This does not seem to have solved my problem.

Thanks in advance,

TheCat

probably .net framework problems, check out the MSDN FORUMS
http://forums.microsoft.com/msdn/default.aspx?siteid=1 or try cleaning up
.net frameworf 1.0, 1.1, or 2.0 using the steps on this page:

According to this:
http://support.microsoft.com/kb/293623/en-us
pdm.dll 6.0.0.8169 has some problems. That's the version on the Visual
Studio 6.0 install. You might be able to use some of the methods in that
article to get an updated version onto your system, then the VS6 install
won't try to update it. Updated versions are also in the VS6 service packs.

You probably sorted this by now, but for the record, I had the same
issue. It is caused by the registry permissions becoming corrupted
which prevents the dll from registering. Grab a copy of regmon from
www.Sysinternals.com, then use regsvr32 to register the dll manually
from Windows\system32. Regmon will show you which keys have access
denied (set up process filtering to just show regsvr32 or the console
gets swamped) then you can use regedit to alter the permissions and
delete the offending keys.

Thanks to thebadger!!! The information at the end of his post solved the
problem for me... Not to mention the fact that I now have a new understanding
of a great way to use regmon to solve similar issues. Thanks again :)
