Thank you for your help!!!

You can't launch at all even on a new install?

Thank you for your answer.

I've tried a new install, but i've got the same problem :  Runway can't be launched...

Could you please erase (make a backup if necessary) the content of  "C:\Users\'YourName'\AppData\Roaming\mGalaxy" (with 'YouName' being your user name on the computer)
...then start mGalaxy_Runway again or proceed to a fresh install then run)
