How to fix Quickbooks error 1603?

I have been having trouble installing QuickBooks. I get this problem each time I try to install or update, which suddenly causes the process to end and displays the message “Quickbooks error 1603: A fatal error encountered during installation.”

After I made multiple unsuccessful attempts to reinstall Quickbooks, I attempted a few fixes, such as turning off the antivirus and firewall software, but it didn’t work. I also tried uninstalling the older version of Quickbooks in case it interfered, but that didn’t work either.

I must get Quickbooks functioning correctly, but I’m not sure what to attempt next. Do you have any ideas about what might be triggering this and ways to resolve it?
