FWIW...
In my case...
Workstation Pro 15.5 reported a new version (15.5.1) and I selected to run the update.
I was looking at a "Finished updating VMware Tools for Solaris" panel for some 5 minutes or so.
Nothing happened.
Then I discovered there was a setup panel, hidden behind others. Okay, I missed that one.
I clicked on [Next] and got a popup "Stop the following process or processes..."
Clicked [OK]
Got back to the setup panel.
After a few tries back and forth, I clicked on [Cancel] and downloaded / used the full trial for the update from:
https://www.vmware.com/go/getworkstation-win
File: VMware-workstation-full-15.5.1-15018445.exe (541 MB)
It requires to enter the key.
Things went fine after that.
