When starting AE I get this message:
After Effects error: Crash in progress. Last logged message was: <4332> <GPU Manager> <2> Sniffer Result Code: 1
The only time I can get AE to start is if I open it as soon as I turn on the computer. Any attempt to open it after that results in the above crash message. This is on my laptop. I had a similar problem on my desktop a few months ago that was fixed after a couple of hours of trial and error by the technical help people.
Same old, same old: Update your graphics driver, configure it properly and turn of the internal intel chipset in the BIOS/ EFI in dual GPU configurations...
