I have Parallels Desktop 6 (6.0.11994) installed and after an upgrade to Lion, whenever I start Parallels, I get these two messages:
Then Parallels Virtual Machines window appears but neither of them can be started.
How do I fix this?
You don't have the Lion compatible version of Parallels installed! The current version is 6.0.12094.
You can download the latest version from Parallel's download page or use Check for Updates... in Parallels Desktop menu.
There are several solutions to this problem.
The easiest, and permanent solution is to upgrade the Parallels to the latest build.
To upgrade, go to the download page or click Check for Updates... in Parallels Desktop menu:
If you don't yet want to upgrade, you can use a workaround below:
The new launcher will appear in your Applications folder and you will be able to use it to start Parallels. You will need to enter your password once before the start because the script needs administrative privileges.
Note that there are also other problems with Lion incompatibility in versions prior to 6.0.12094 and this only fixes startup. I also had a problem with Parallels virtual machine window being only briefly visible during Spaces transition, as if it were above all windows in the system. Apparently, I had Coherence mode set by default, and there seem to issues with it on the older versions. I fixed the problem by clicking the red Parallels icon in the menu bar and choosing Exit Coherence:
To fix the same issue with Parallels configuration window not appearing, I had to change Assign to from None to All Desktops.
