My 4.0 version (latest build) of Parallels has been working well until recently. All of a sudden the Coherence switch is disabled (the drop downs greyed out) and will not work. The size of my screen, which has fit my mac, suddenly is larger.
I uninstalled Parallels Desktop and uninstalled Parallels Tools from Windows and reinstalled Parallels ok. However, Parallels Tools won't load giving me an error saying Windows could not locate the installer for mouse, the mouse driver won't load, and the class installer registry item is invalid. The Parallels Mouse Synchronization device is installed (4.0.3813.40912), but I cannot uninstall it or do anything with it because I get a message saying windows cannot locate the installer for mouse.
I tried reinstalling Parallels Tools several times but keep getting the messages about no installer and registry item invalid. I also tried unchecking the capture and replace mouse pointer item in configure, but that did not help.
I am using Windows XP Home all updates, latest version of Leopard and a Mac Intel 2.16 ghb intel core 2 due with 4 gb ram.
Ideas on how to fix?
