I\'ve tried to install Visual C# 2010 Express edition onto my PC, but whenever I try to run it, I get a error message.
Invalid license data. Reinstall
An another solution I have found to work is the one mentioned Mac by over at SuperUser: https://superuser.com/questions/651261/how-do-i-fix-an-invalid-license-data-reinstall-is-required-error-in-visual-s
When simply reinstalling the Visual Studio 2010 shell doesn't work, he points out that installing it through SSMS 2010 can solve the problem:
I was able to resolve my issue without making any manual changes to the Windows Registry by installing SQL Server Data Tools 2010, which is also free and includes the Visual Studio 2010 Shell.
You don't have to go through the entire install process. I cancelled the process when it was done installing the shell and it worked our fine.
