By golly I did try ANYTHING and was successful in downloading the 2021 software on the very link as provided by another fellow. UREKA !!! AND i QUOTE Brian B. as follows:
Posted January 12
I had the same Not Responding problem during the 2021 install procedure, I emailed Support twice and the second time I received several links to try.
Their last link worked: https://cdn.ufile.ca/ufile/UF2021BNGH36GHVFENB469KL3CMO9/ufile2021.zip
After I unzipped the file I clicked on the MSI file to start the install, it took a while to get going but it finally installed ok.
Just press this link. It works!!! The others are corrupt.
