I have always upgraded LR and PS via the "Help/check for updates" dropdown menu, as I did last
Thursday evening...didn't get around to checking things until Friday morning...PS would not open.
Linked-up with Adobe tech Friday morning...duration 4 hours...it then opened with some glitches.
Relinked for an additional 4 hours during which they un/reinstalled both LR/PS and...left a lotta
junk on my desktop.
Relinked with my desktop again this morning...2 hours during which he fixed everything,
including all updates. Lesson learned...all tech people are not created equal.
