I have two Windows 7 VMs installed under MacOS Mojave and Parallels v16. I am unable to install the Parallels Tools in either VM. Generally the installation gets to about 60% on the progress bar and then an error message ("a problem occurred") appears and the only option is to reboot. This reboot sometimes resets things like the Windows screen resolution. I have tried all of the troubleshooting options here: https://kb.parallels.com/8969. They all result in the same error. Any other possible work arounds to this?
