How do I fix an “Invalid license data. Reinstall is required.” error in Visual C# 2010 Express?

Question

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

Answer 1

It was not the clock for me, and all the hours spent re-downloading and reinstalling were a waste of time (except for the last one, of course....).

Also, for some odd reason, just adding Read permissions to the HKCR node using psexec -i -s regedit did not work by itself.

To fix my problem on Windows 7, I made sure (using psexec -i -s regedit) that my login account had full control permission over every node in the registry and that the everyone group had read permission over every node in the registry, and did all of the steps in the following link (rebooting after each step):

This is probably overkill, but after spending 10+ hours trying to get this working, I am just happy it works... Good luck!
