I tried all the suggestions and tips at other threads also regarding update issue for Turbo Tax Home and Business 2022 Desktop edition.
After spending considerable time - almost 4 days and multiple hours, I changed the TEMP and TMP location also but that didn't solved the issue.
I tried on my new desktop where there are no prior version of Turbo Tax Home and Business Desktop edition(I am using it since 2012 and prior to that Deluxe Desktop edition)-it worked.
So it's the previous versions of Turbo Tax Home and Business Desktop editions which is coming in the way of installation and update of Turbo Tax Home and Business 2022 Desktop edition.
Shame on intuit that they are not doing this kind of testing and expecting customers to fix this kind of issues. Logs doesn't contain something meaningful for the person in IT to also fix.
Better to uninstall all the prior versions of Turbo Tax Desktop edition if you are also facing this issue.
