Hi,
Hi Fredrik - I apologize for the delay in responding. If restarting your computer does not solve the issue, there may have been a problem with the installation. Remove LEAP from your computer, and then run the LEAP installation file as an Administrator to ensure the registry keys install properly (make sure you have Administrative rights to your computer, and are logged on as the administrator). To do this, right-click the LEAP setup.exe file, select 'Run as Administrator' and re-install LEAP. Hopefully this helps, but please let us know if you still have problems opening LEAP.
I also had the same problem. I found the solution.
