Karl, thanks for this last suggestion. Very simple, but it worked! Twice during installation, I received a message "Error 1406. Could not write value to key \SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\AcrobatInfo.exe. Verify that you have sufficent access to that key, or contact your support personnel.". The available options were Abort, Retry or Ignore. Retry proved unsuccessful, so I chose Ignore. Installation completed successfully. It's installed Acrobat Reader continuous release version 2023.001.20064 64 bit, rather than Reader DC, but it doesn't seem to matter. The interface looks the same/similar. I loaded a document as a quick test, and it seemed to work fine. So thank you very much for that. If I ever run into that problem again, this will save me so much time, and I hope that this page will also save time for others who come across the same problem. For reference, the path I found the setup.exe file in was C:\Program Files\Common Files\Adobe\Acrobat\Setup\AC76BA86-1033-1033-7760-BC15014EA700, so the directory structure in Windows 10 is obviously a bit different from Windows 7.
Thank you very much for the time and effort you put in to help me with this. I'm glad that it paid off. Best regards, Martin
