Problems in VS after installing VS 2010 Beta and SQL Server 2008

[pnunbe]

Hi,

I succesfully messed up my installation of VS (2003,2005,2008) and SQL
Server 2005.

First problem: after installing and uninstalling VS 2010 beta, all my
installed version of VS failed to launch due to a missing 'msvcr100.dll' file.
I then downloaded this file from the web into 'c:\windows\system' and VS now
works all right (but see below) , but I wonder why msvcr90 and msvcr80
apparently no longer exist in my system.

Second problem: I tried to update SQL Sever 2005 to 2008 and everything was
apparently OK, but the database engine version, as displayed in SSMS, was
still 9. I then removed 2008.
At this point I still have a working instance of 2005, but I cannot
uninstall it, not even using the procedures outlined in:
support.microsoft.com/kb/909967.
Another side effect of this problem is that I cannot create an SQLConnection
in VS's Server explorer, the error message being (free translation from
Italian):
"Cannot load file or assembly 'Microsoft.SqlServer.Management.Sdk.Sfc,
Version=10.0.0.0.0, Culture=neutral, PublicKeyToken=...' or one of its
dependencies. Cannot find the specified file"

Any suggestion?

Regards

I'm sorry I can not help you with your problem, but you have helped me with
mine. I too downloaded and installed the vs 2010 beta and upon uninstalling
it, no other version would install b/c of a missing msvcr100.dll. Your post
is the only one I found that actually said where to place the dll. I had
downloaded it but had no idea where it needed to be placed to be read. I've
never had this issue before. Now VS2008 seems to be installing just fine.

Thank you so much and I hope you get the answer you need soon.
