Parallels recently updated itself, and I can no-longer get parallels Tools to install. When I hit install parallels Tools, it unpacks the installation, and proceeds to try to install, however while the status says "Removing Applications" it pops up a box stating that "the feature you are trying to use is on a network resource that is unavailable" asking for 'setup-parallels-tools.msi' the suggested source is C:\WINDOWS\Temp\ , and browsing, the file does exist. Selecting it, I get a message: " The file 'C:\WINDOWS\Temp\setup-parallels-tools.msi' is not a valid installation package for the product Parallels Tools. Try to find the installation package 'setup-parallels-tools.msi' in a folder from which you can install Parallels Tools." When I hit Cancel, the install fails (with the message "Error 1714. The older version of Parallels Tools cannot be removed Contact your technical support group"), and after I hit OK, it brings up a message that parallels tools installation failed, and reboots the virtual machine. The same thing occurs if I try and trigger the install by mounting the .iso file from \Library\...\prl-tools-win.iso and running setup.msi from it. I can't uninstall parallels tools. the message is "Parallels Tools require that your Windows is running under Virtual Machine. The installation will be stopped." (I am running it within the virtual machine) any suggestions or help on what I can do to resolve this?
