I was able to uninstall VMware Workstation 12 Pro (v12.5.7) after a significant amount of effort (it stubbornly refused to uninstall completely - see Cleaning up after an incomplete uninstallation on a Windows host (1308) | VMware KB), clear out all the old drivers (using Windows 10 safe mode because 1308 did not work completely), and re-install Workstation 12 Pro version 12.5.7 build-5813279. The failed upgrade rendering the software absent and missing devices constitute a pretty crummy upgrade experience, I hope you guys make this more robust. At that point I thought I'd installed successfully, but apparently not since I hit the issue described in this thread. I dug the installer file out of the temp folder and ran it again, and when I got those warnings I started killing random processes (not VMWare, which I'd already shut down) via process explorer until retrying worked. I lost half a day trying to solve this though, and was dreading going through the same reinstall process you did.Īdditional data if it helps anyone - my original installation had failed due to me clicking 'Ignore' on a warning about the installer being unable to install some service, resulting in VMWare being absent from my machine. I solved it by going to 'Programs and Features', right-clicking 'VMWare Workstation', choosing 'Change' and then then choosing the option to repair the installation.

I had the same issue after upgrading to 12.5.
