Virtualization support disabled after upgrading to Lion, Parallels Desktop 6 will not resume my virtual machine, Virtualization support disabled after upgrading to Lion, Parallels Desktop 6 will not resume my virtual machine

Make sure you have updated to the latest version of Parallels. It is working fine on my Lion install and has been working for a couple of months now. It seems that the version of Parallels you probably have is not the most recent as that was the error message that I an others received when we first installed Lion. I suspect that is the problem. The Parallels build I am running that works with Lion is 6.0.12090.660720

This should solve your problem.

Glad I could help

I have a similar problem with a mid 2010 MacBook Pro. Just installed Lion, then tried to check Parallels 6. There is no virtual machine window at all. However, there weren't any messages either. I did check for updates and installed the most recent build (same as above) but that didn't resolve the problem. Parallels seems to open but there's nothing on the desktop. I tried to select Configure from the Virtual Machine drop down menu and now all those options are grayed out.

The Parallels website isn't very helpful. My only virtual machine is Windows XP.

I'd like to be able to use the program again - carrying a 2nd computer for work just isn't worth it.

Problem solved. It seems Mission Control was cloaking the virtual window. I went to the Mission Control settings in System preferences and deselected some of the standard options -Show Dashboard as a space & Automatically rearrange spaces based on recent use. Then deleted all the extra Desktops (4). When I worked with Mission Control again I got an option to go Full Screen; and there was the virtual window. It was waiting to finish installing updated tools and needed me to OK the process. Once that was complete, all was well.

Lion is great. And now Parallels is back. I'd still rather not do Windoz at all, but at least we can have operating systems that coexist.

Thanks to the community for being here. Peace!

This post was incredibly helpful! I have a mid 2010 27" iMac and had the same issue with upgrading to Lion. The first answer was spot on... I opened up Parrallels and updated, wha la problem fixed. Thanks so much!

I am now having this same problem after I updated my mac OS X Mavericks.

Are you using the current version of Parallels, which is Version 9?

Okay I did update to Parallels 9, but now I can't find an excel file that was on my old Parallels desktop. Is there anyway for me to get this file back?

So you're saying that Parallels 9 works in your new installation of Mavericks, you can now use it to open whatever virtual machine you were using with whatever earlier version of Parallels you were using before you upgraded to OS 10.9, and when the virtual machine's own desktop appears, your excel file is not where you left it? If I didn't fill in the blanks correctly, please do so; it helps in troubleshooting.

Yes my parallels 9 is now working on Mavericks. However in order to install Parallels 9 I had to delete my Parallels 7. And you are right it was an excel file and it is not on the new Parallels 9 desktop, but that is what it was saved to on Parallels 7. I realized now that I should have backed up my computer before updating it. But I just still had a little hope that I could maybe find that excel file.

Parallels is a program which creates an environment in which an operating system (usually Windows) can run on a Mac. The Windows virtual machine which the Parallels program creates is stored in your Documents folder (Documents/Parallels). When you run the Parallels 9 installer, it asks if you want to remove a previous version of Parallels (that appears to be optional), but if you do, the installer does that automatically; there's nothing that you have to delete by hand yourself. All that gets deleted is the old program (i.e., Parallels 7). Your virtual machine files aren't touched and should still be present in the Parallels folder inside your Documents folder.

What you're calling the "Parallels desktop" is actually the Windows desktop which appears when Parallels starts up Windows; you probably have Microsoft Office installed in Windows, which is what you used to create the Excel file. Assuming you didn't delete that Parallels folder inside your Documents folder, the Windows virtual machine should still be there, with the Excel file still on its virtual desktop. With Parallels 9 running, you should be able to open the Windows virtual machine that's in that folder and run Windows, and the Excel file should reappear.

Okay so I go to document but when I click on the Parallels folder inside documents, it just opens up the parallels application which is Windows. There are no files there and the files do not come up in Windows either. I do know what the name of the file was but I have searched for it under all my files but I can still not find it.

What's inside that Parallels folder is the entire Windows virtual machine (if you Get Info on that Windows file, you'll see that it runs to GB's in size, which is pretty big).

When you say "the files do not come up in Windows either," do you mean that you have Windows running, complete with the Windows desktop and its Start Button but that Excel file isn't on that desktop?

I mean that it is not on that desktop when I have Parelles running on my full screen the excel doc. is not there and it is not there when I search all of my files.

Did that help at all?
