Trying to reply to my own post from July 11, 2022, but the forum keeps putting it here.
Again! Just did the the latest update. QB Premier 2021. QB now can't open our company file. Their diagnostic utilities just give useless / false information and steps that accomplish nothing. When using a "standard" Windows account the QB update will only work if QB is started with "Run as administrator" (using mouse right click on the icon). BUT don't do it!
After the update and required reboot, upon trying to open our company file QB gave me an error about being unable to communicate with the "server".
Tried my above "solution" but this time it didn't work. Same message about being unable to communicate with the "server".
After trying various things to open our QB file, including using a Windows administrator account (instead of the usual "standard" account)...
1. Rebooted again.
2. Logged into a Windows administrator account on the server computer.
3. Cleaned out from the QuickBooks folder a bunch of old unused company and related QB files (moved them into a subfolder) and other old unneeded files.
4. Opened the company file in QB on another computer after it had been updated -- It opened with no problem.
5. Opened a different QBW file on the server computer. It worked.
6. Opened the problem company file. It worked!
7. Logged back into my usual "standard" Windows account. QB opened the company file with no problem.
I have no idea why it works now. And neither would anyone else including Intuit!
From now on I will do the QB updates in a Windows administrator account. (If you always run QB in an administrator account you probably aren't running into this issue.) Hopefully QB will work properly the next time without any problems.
