Hi

I'm sorry for the frustration.

Can you 

- Open File Explorer

- Type %LocalAppData%\Intuit\proseries\2020\telem_log

- Email the ProSeries Installer_2021_2_9.log file you find there (name might be slightly different) to me at proseries_engineering@intuit.com

- Then backtrack to AppData\local and email me IntuitProSeriesTY20Installer.log

This will help us troubleshoot. Alternatively I suggest calling into customer support tomorrow.
