How do I fix this?

How do I resolve this issue, I never had this issue before.

[The project cryptlib.vcproj appears to be under source control, but no source control provider is installed on this computer. Source control integration will be disabled for this project.]

Then when I click ok, it just close. Any idea? Thanks.

BUMP! I still cant figure that out on how to fix this... I've tried to reinstall it about 5 times. Its a issue with a source control or something..
