After Effects won't open

[gkolisch]

It simply doesnt start. Tried reinstalling it.

Have you tried resetting your preferences?

Press Alt (Windows) or Option (Mac OS) while launching After Effects. You can release the Alt or Option key when the splash screen appears.

To reset preferences and plug-in cache at the same time, hold down Control-Shift-Alt (Windows) or Command-Shift-Option (Mac OS) while the application is starting. Release the keys when the splash screen appears.

If that doesn't do the trick - do you have any third-party tools installed? Try uninstalling those and try again.

If these don't solve the issue - any chance you're on Mac?
