ACC app will not open and will not resinstall

[exbrooklyn98]

I get messages telling me apps like PS need to be updated but when I try to open ACC nothing happens! I tried opening PS itself and doing the update that way and STILL nothing happens! When I tried to reinstall ACC I get a message telling me an installer is already running. This is REALLY frustrating!
