Failure of attempted upgrade to Fences Version 3.13 from Version 3.0.9.11.
Version 3.0.9.11 worked OK and still does. The installation of Version 3.13 seemed to go ahead normally until the following error message appeared:
"The uninstall executable file could not be written because it is already in use. Close all running uninstalls and click Retry to continue. Click Cancel to abort."
As no Uninstalls were running I had to click on Abort. A reminder to install the new version is naturally presented on every boot-up of my "W10 64-bit, Home, Version 20H2, OS 19042.1165" and always produces the above error message.
I would be happy to permanently stop the reminder message if I could, but ideally would like to install Version 3.13 if I could be certain of being able to return safely to Version 3.0.9.11. in the event of problems.
Any help will be gratefully received - thanks in anticipation.
