    VMWare Machine Crashing Routinely - "Invalid MKSWindow definition" error

    conradclose Lurker

      I'm running VMWare WorkStation 15 Pro version 15.5.1. My virtual machine is running THEOS as a OS, which I realize is unsupported, but it's the only OS my software will run on. The software my company uses was built in the 80s, and designed specifically for THEOS. So a different OS is not an option.

       

      Every day, the virtual machine freezes up multiple times. The timing is random, and isn't linked to any user activities. Note that VMWare is still functional, but the virtual machine itself locks up and the only way to fix it is by powering down the virtual machine and restarting VMWare workstation. I've attached the full log file, but here is the relevant portion. This error sequence shows up repeatedly any time the machine crashes.

      I've reached out to VMWare support, but they won't help me due to the fact that I'm not running a supported OS. Hoping someone here has had a similar issue. Thanks in advance!
