Updated to PS2018 and Creative Cloud apps stopped working.
@
It has been over a week of wasted hours with Adobe techs changing permissions back and forth on my computer and still nothing works on CC. Everything was working perfectly until the PS update so I can't think of anything else that could have caused it. When you chat with support they always do the same thing: They ask to get into your computer, rummage around for a while, change permissions, and an hour they get exactly the same Error 16 message. NOTHING CHANGES. After they waste your time they send you a link so you can waste your time trying to do the same thing they just did some more.
Today I decided that if I would get no help from Adobe, I would just wipe my computer as a last resort. I contacted support to ask for advice and the tech asked to get into my computer again. I explained that it hadn't worked before but he insisted saying If you allow me, I will fix this for you. In desperation I agreed. NOTHING CHANGED. Same useless link at the end, and never answered the question I contacted him for in the first place.
I own a small business that relies heavily on the Adobe suite to survive. It is inexcusable that Adobe can't offer adequate support for a product for which there isn't much of an alternative, and instead give their customers time wasting runarounds.
If there is no solution for the issue, I wish Adobe would just say that and let their customers go instead of wasting their time.
