[resolved] Quickbooks Desktop no longer working after 26.1.2 upgrade

FYI, when the problem occurred for me all of the QuickBooks files were in the VM's local C: drive and the problem has already been identified as being caused by the November 2025 Windows 11 update which was incompatible with Parallels v21.1 or later. This has nothing to do with shared folders or drive mappings or with Windows permissions to the file location or with the file not being in the local VM C: drive.

Hey all,
Helping my mother-in-law get QB Pro 2021 installed in Parallels and running into an ever-loading activation screen which I'm chalking up to this bug. She was running 26.1 initially. Steps taken:
1. Switching emulation to Very Strict and rebooting the VM, no resolve.
2. Downgrading to 26.0.1 and re-activating did not resolve either (tried both default and very strict emu)
3. Ran QB as Administrator in all situations.
4. Windows Firewall was disabled the entire time.

Anything else I'm missing that's worth a try? I have an IT background and even I'm stumped! Hoping to see Quickbooks mentioned in the changelog on Parallels 26.1.3....

 

Unfortunately, the 26.2.0 update doesn't mention anything about fixing this interaction bug with the Windows update that breaks opening company files in QuickBooks Desktop. So after downgrading, you have to skip/ignore their upgrading request. You also need to turn off automatic updating in the Parallels Desktop - Preferences... - General - "Check for updates automatically". I suggest turning off Windows "Virus & threat protection settings" - "Real-time protection" since I find that having that on can significantly slow down installations. I don't know about activation, however, but it's worth a try.

 

I installed the 26.2.1 update and my company file loaded properly so this appears to be working. Thank you for fixing it.

 

Worked for me. Updated Parallels to 26.2.1, updated Windows 11 to the latest, ran QuickBooks Desktop Pro Plus 2024.
Loaded Company file fine. Before would get stuck on open.

 

Worked for me too. Wow, that was quite a scare! Thanks for fixing it Parallels, but disappointed is broke in the first place.

 

Anyone having new issues with update to 26.2.2? I'm getting error messages in Windows after it rebooted overnight about missing dll files for both adobe and quickbooks.

 

Really? I'm on 26.2.1 and not updating till I hear from others

 

This is not working for my customer. He bought his copy through the app store and says version 1.26.2. NOT 26.2.1 or 26.2.2. There is NO check for updates, so how in the heck are we supposed to fix this? My customer is down right now, and the fact that we can't reach support is ridiculous. Can't even email them!

 

Is anyone else on Parallels 26.2.2 and experiencing issues with Quickbooks 2024 Desktop Pro?

 

Has anyone tried Parallels 26.2.2 with latest Windows 11 and Quickbooks Desktop Pro 2024 and DIDN'T have and problem?

 

Just to close this, I myself upgraded to Parallels 26.2.2 (57373) and haven't experienced any issues with Windows 11 or Quickbooks Desktop Pro 2024.
