Program not launching

[ahatem]

I am unable to launch CloudCompare on my my computer all of a sudden. I uninstalled, and downloaded the most up to date alpha and stable versions and still was unable to launch. The program worked just a few days ago and now I can't get in. Is anyone else having this problem or have any suggestions? Thanks,
Alex

Was the graphic card driver updated maybe? (what card do you have?)

Another option is to delete all information in the registry (delete the CloudCompare folder in 'HKEY_CURRENT_USER\Software\CCCorp').
