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 is required.

I've already tried reinstalling it, and the message persists.

OS is Vista Home Premium. I already have VC# 2008 Express installed.

I am using Visual Studio 2013 and I have the same issue but it occurs when I try to open a solution that was made using Visual Studio 2010.

The solution for me is to open the solution file (.sln), using notepad and change this line:

[# Visual Studio 2010]

to this:

[# Visual Studio 2013]
