Requirements to Reinstall Acrobat XI Pro?
**What are the required documents and credentials to reinstall Adobe Acrobat XI Pro from scratch?**
As explanation, for several years Acrobat XI Pro has run flawlessly on this computer, long after my upgrade to Windows 10.
However, now when using a Canon LIDE-120 to scan to PDF (a common and always successful activity here) Acrobat XI crashes without explanation. No error messages are provided. Win10 continues to run fine.
This is a problem noted by a number of posters to this community dating back to 2017.
The Adobe's modify/repair applet in Windows 10 under Set-up|Apps and Features "humps" on Acrobat XI for several minutes, reports that its effort was successful, but afterward Acrobat XI still crashes as it did before.
I long ago lost the shipping carton, diskette and keycode for this copy of Acrobat XI. How do I recover the key code so that I can reinstall it?
While searching on Help|About I just noticed that this problem is not specific to scanning as I mentioned. Acrobat XI Pro crashes as a result of various activities within Acrobat XI. If my keycode is listed in Help|About the program does not last long enough for me to read it.
