Hi there, after i've installed Parallels on Ubuntu 7.10 the Version 2.2.222 is running very good. But after updating the Software over synaptic, I've installed three parallels packages. # parallels 2.2.2224-1gutsy1 - https://lists.ubuntu.com/archives/gu...ry/010148.html I got the following error when i'am start my VM Parallels Workstation Error occurred while trying to interact with Parallels driver! Parallels Workstation is either not installed or/and configured or has integrity problems, which prevent it from operating properly. Please reinstall the Parallels Workstation. If i uninstall the packages and install again the version from your download section all is working again. I've tryed that on my 2 PC's. First fresh install. Same Error Second update over existing Parallels Version. Same Error. Could you help me out, so that i could use the newer Version (updated packages) please. many thx in advance Regards Frank
