@Phil You need to get an older version of the uFile install program - like from 2019, use an archive extract tool, like WinRAR or 7Zip, extract the .exe installation file into a directory. Then do the same for the 2021 .exe installation file. Once you've done that, you'll have 2 directories, one for 2019 and one for 2021. Go into the 2019 one and find the "NDP452-KB2901907-x86-x64-AllOS-ENU.exe" file. Copy it into the 2021 directory. Then in the 2021 directory, edit the 'setup.ini' file and replace the last line that says: Prerequisites=EdgeWebView2 to Prerequisites=Netfx45
Once you've done that, click on the 'setup.exe' file in the 2021 directory. I should then install uFile 2021 correctly.
Good Luck!
