We've had problems with trying to upgrade to QB 21 from QB 18. All Enterprise. Company file 1.4 GB.
Symptom was that we would open the company file and the system would immediately crash, within a few seconds. Our IT consultant has been on the phone with QB Support numerous times. I've been on the phone with QB support numerous times. Opened up several cases. Every time we'd call again and reference the case we'd be told that nobody had written any notes and then we'd have to start all over again with a new support person. No continuity.
I had our IT consultant put the application and the company file on my machine. Did all of the usual Verify, Rebuild, File Doctor tools. Looked at Windows Event Viewer and noticed that there were a lot of security events that occurred just before QB crashed. Had the IT consultant disable our antivirus (Trend Micro) and was able to get QB 21 to open and stay open. I exercised it many times, but could not pound on it like a production environment would, and everything continued to work.
Came in this morning and rebooted my machine, the antivirus services were running, and boom, wouldn't work. Contacted my IT consultant and had him uninstall Trend Micro, and was able to get everything working again.
The next step was go back to the company file that we had sandboxed on our server and try to access that from my desk top. Got everything to work without crashing. Exercised it many times, but again, not a production environment. After looking at Event Viewer on Windows each time, I would have the same two errors, although QB 21 would start up and work fine (for the things I did on it). These errors were both the same, always paired: An unexpected error has occurred in "Intuit Qickbooks Enterprise Solutions: Manufacturing and Wholesale 21.0": Got unexpected error 5 in call to NetShareGetInfo for path \\"server details"\"folder details"\"companyfile.qbw" (things in " " are our server name, company file name). Always the same errors, but QB worked.
Tried running QB Tool Hub/Installation Issues/Quickbooks Install Diagnostic Tool to see if there was a problem with my desktop install and it found no errors. Re-ran test above and got same two NetShareGetInfo errors.
If we could get rid of those 2 errors, and figure out how to run our antivirus (could just be a configuration error) without it crashing QB, we could probably do a production test. I hope this is of some help to some of the folks on here.
To Quickbooks Support personnel reading this: While you are all lovely people, please do not respond to this post by suggesting that we call QB Support. Been there, done that. Spent probably 6 hours on the phone, over all the different times I've called. There is no continuity, no taking of case notes, no reading of case notes. It's like I'm starting from scratch every single time I call. That suggestion is of no help.
