I haven't used CCC for months, and today I wanted to use it (new additional screen) but it didn't start...
When I double clicked it, the cursor changed to the waiting one for a second then nothing. The process was here but there was no windows opening.
I tried to kill the processes (except one which doesn't want to die, "host application") and try again but without success.
After that, I upgraded CCC and the driver to the last version (without .NET 4.5), same problem.
I uninstalled CCC and the driver and installed it again (with .NET 4.5 this time), same problem.
