You've hit the nail on the head. At least 1 engineer is crap! and has some bad code that creates this issue. It's not every update, and in this case, I have a system with Enterprise 23 and Premier 23 installed. Only the Premier version is experiencing this issue.
Furthermore, I've given "Everyone" full access to C:\Program files\Intuit, Program data\intuit and gave the QBdataService user admin rights and full control on all folders in the data folders area.
I've been seeing this issue for at least 3 years now. I'm an IT Support professional and used to support software engineers. I can almost guarantee some relic has bad code that is added randomly. Other developers probably remove it sometimes, but it's never gone completely.
