Having the same issue the last couple days. All of my other CC apps run fine, but Premiere wont even open/start (not responding). Have tried all of the solutions I've found on the forum (including reinstalling older versions) but still nothing.
Also, it's not my system either as I have a newer Dell with more than the recommended hardware with 64 GB of RAM. NVIDIA card.
By the looks of the forum this has been an issue for the last year. Hopefully you (we) can get an anwer that works at some point.
