Comment 83 for bug 365881

I am running Windows 7 Ultimate on a 64bit AMD PC and got the same error when starting the Wubi.exe as Administrator, so I thought what else can I do and first tried it with running the file as normal user. Result: The same problem.

Then I did a right click on the file and found another option by trying the Troubleshoot Compatibility Problems option. This option proposed me to run Wubi.exe in the Windows XP (SP2) mode and yes, the complete problem did not arise!
