I just upgraded my Parallels 9 (latest update) to 10. When I click to start up my Windows 7 VM, I get "A critical error occurred with Parallels Desktop." I've submitted the generated reports a couple of times.

Any suggestions to try to get my VM working again?

Thanks,
Peter
 
Ok, I got it started in 32-bit mode! It churned quite a while before it started. It's installing the Parallels Tools now. When it's done, I work in Win 7 a while, and then shut down and try to start in 64-bit.
 
Start Parallels
Open the settings window
Select the Hardware tab
Select Boot Order
In the Boot Flags box, enter: vm.app_mode=32
Now try starting your Windows VM (it started up for me, but it took a while)
Shut down Windows
Go back to the Settings Hardware tab, and clear the text from the Boot Flags box
Start Windows again
Everything was fine for me after that.
