CS5.1 extended won't take serial number since W10 anniversary update
I'm running the latest update of Windows 10. I've been running CS5.1 with no problem for years on Windows 7 and then Windows 10. Since the annivessary update of Windows 10 when I try to start CS5.1 I get a message saying my trial has expired and asking me to provide a serial number. I do this, and since it was installed as an update, then get a window asking for my CS2 serial number. This has always worked in the past when I reinstalled. Now, however, it simply recycles back to the screen saying my trial has expired - repeatedly. I've tried the troubleshooting steps in the common problems, including accessing https://adobe.com, to no avail.
As an aside, I had a problem with Acrobat 8 standard that occurred with the anniversary update. I had to tell it to "never register" every time I tried to open it. There was a registry edit fix published for this, and it worked.
Is there a similar registry edit fis for the Photoshop problem?
