Quickbooks Desktop no longer working after 26.1.2 upgrade

This morning I *Was* able to fix this using the posted directions from @CoryL1

Here's how to find the Emulation Settings thing!

Find your QB App in Windows (In my case it resides in "C:\Program Files\Intuit\Quickbooks Enterprise Solutions 24.0\QBWEnterprise.exe")

Right Click and choose Properties

Click the Compatibility Tab

Under the section called "Windows on Arm" click "Change emulation settings"

You will see a pulldown with an arrow that likely says "default"

Click that pulldown and you should see the "Very Strict execution" choice at the bottom of that list

Choose that, hit OK, Then Apply, then reboot!

Hopefully this will work for you!

 

Got mine fixed by installing PD 26.0.1. The very strict execution just fails after some dumb windows update.

 

See the BEST ANSWER above in this thread that refers to https://kb.parallels.com/en/131061 which has a link to a disk image installer for v26.0.1.

 

I have had the same issue. Company files would not load. My IT person spent 10 hours looking into why. QB said it was my company files. I had to go buy a Windows Computer just to work on my company files. So I have spent a lot of money with buying another computer and paying my IT person as well as my time talking with QB and the downtime of not being able to work on my clients files. This is pretty sad on Parallels part not to have this fixed yet. I keep looking for the update to fix this mess and so far nothing. I have been using Parallels for over 15 years and not once have had an issue. This is a serious issue they need to address.

 

Did you see the BEST ANSWER above in this thread that refers to https://kb.parallels.com/en/131061 which has a link to a disk image installer for v26.0.1? That downgrade to an older Parallels version worked for me.

 

I have tried to find the version to downgrade to and it doesn't let me download it. The download button is greyed out. I checked my subscription and it is still good. Any other ideas?

 

Did you see the BEST ANSWER above in this thread that refers to https://kb.parallels.com/en/131061 which has a link to a disk image installer for v26.0.1 in the "Alternative workaround:" section that says "Download Parallels Desktop v26.0.1"? That downgrade to an older Parallels version worked for me.

 

In particular, the text "Parallels Desktop v26.0.1" is a link to the following: http://download.parallels.com/desktop/v26/26.0.1-57243/ParallelsDesktop-26.0.1-57243.dmg

 

Parallels folks, please fix this soon. I am using the workaround, but it makes QuickBooks so slow as to seriously impede the ability to get work done. This is the only reason I have had Parallels (and I suspect there are many other Mac users who only buy it to use QuickBooks). I don't want to have to get rid of Parallels and go to using QuickBooks online instead, but I can't work this slow for much longer. Just saying...

 

Instead of using the first alternative of changing the emulation settings to very strict execution, put that setting back to Default and try instead the Alternative Workaround which in the KB article https://kb.parallels.com/en/131061 has a text link "Parallels Desktop v26.0.1" to the following: http://download.parallels.com/desktop/v26/26.0.1-57243/ParallelsDesktop-26.0.1-57243.dmg
That worked for me and does not appear to have any performance issues.

 

Thanks much. However, that did not fix the slowness. It takes forever to open up everything on a company file, even on a very small company file. I never had this problem before. I have tried everything (file repair, etc.), plus changing Parallels memory settings, etc. Nothing works.

 

Ah. Relief at last! My fault (as usual)- I am now sent to adult time out to pay for my mistake. it had compatibility mode selected. Once I unchecked that things sped up.

 

That's great! Just so others are aware, changing the compatibility emulation setting requires restarting the Windows virtual machine for it to take effect. This isn't the issue you had (you just didn't have it set back to Default) but people should not expect to see a change just when they change the setting until they restart Windows.
