Has anyone had this problem? I'm using Parallels 9 on a MBP running Yosemite, which I use for Revit and Microsoft Project. I can start the VM, but all text appears as a series of boxes, slashes, and symbols. I tried to launch Windows troubleshooting, but nothing happened, nor did Parallels guide for repair via the terminal. This happened once before quite some time ago, and I really don't want to reinstall everything.
Hi Stowe Teti, Could you please provide us a screenshot of Windows screen when you face this issue, so that we can help you better.
