@anon818964, I am able to recreate the problem and have created the following Paratext support issue: PTX-21029. Here is what I found about this problem:
The error message suggests looking in Help for how to fix this, but that is not possible, since the program will not start.
I tried to uninstall the program from the Apps & features tab in Windows Settings, choosing the ‘Remove settings’ option. I also tried to clean up left-over registry entries using Revo Uninstaller. But after installing again (not using the /quiet option), the same errors occurred, and the same resources were copied to the root folder!
To get Paratext to open, I had to delete the following key from the Windows registry prior to opening:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Paratext\\8\\Settings_Directory
After opening, Paratext did an automatic download of an update and suggested I restart Paratext. On restart, the registry key got the wrong value again, so I had to delete it a second time.
All that to say, please don’t try using the /quiet feature again on any machine until we are able to fix this bug!
