What I did not love though was after installing Office 2010, my Visual Studio 2010 Beta stopped working, simply displaying the message “Cannot Create The Window”.

Microsoft claimed not to be able to recreate the issue and I was quite happy to wait until another version of VS 2010 was released, but luckily for me, Microsoft have now found the issue.  Apparently, there is a version msvcm100.dll in C:\windows\system32 which is different in office 2010 than in vs 2010.  It also seems that office and vs play nice when using the VS version of the dll, but that VS falls over when using the office version.

Ok, so to the workaround……

You have two options;

1. Replace the msvcm100.dll with this one, msvcm100.zip, I took from my system32 folder. 

or

2. If you would prefer not to use a randomly downloaded dll from here, you can rename the msvcm100.dll in system32 to msvcm100.dll.old and then run VS 2010 setup and choose to repair.  This will recreate the dll.

The working version of msvcm100.dll has a datetime stamp of 6th May 2009 7:20AM.

Well, now my Visual Studio is working again, I am off to have a play!

Enjoy!
