I have repeatedly tried to install Parallels Tools. It can't find the Parallels Ethernet Adapter and then backs out of the install and restarts XP. When it comes back up, windows now can't find my graphics adapter. Have an iMac intel core 2 duo with 3 GB ram. Worked fine before I upgraded to version 6. Have 6.0.11994 Coherence mode also won't work (grayed out). Any suggestions?
Have you tried following the instructions in this article - http://kb.parallels.com/8969? BTW, Coherence mode will not work if Parallels Tools are not installed.
