I need to file a 2020 amended return, but my 2020 TurboTax Home and Business doesn't run.

 It doesn't update.  I downloaded and ran the manual update but the program would not start after the update - the program simply closed. Tried to update in compatible mode but now I receive the error "Sorry but your system doesn't meet the minimum requirements.  Memory (2048MB).  Is there a way to install a clean/new copy of TT 2020 Home and Business?  Or is there a work around to get my copy working?
