29144 error upgrading VmWare Workstation

I tried to upgrade VMware Workstation on Windows 10 from 15.5.0 to 15.5.1. As usual, the installer first removed the older version, and then installed the newer one. But it stopped with error code 29144 and rolled back the installation process. Which resulted in no Workstation version installed.

I tried the method I found suggested on the net, which is reboot between removing the old version and installing the new one. Since I had no more the old version installed, I simply rebooted before tretrying the installation. Which unfortunately yeld the same error.

In my case, the solution was to delete everything in %TEMP%, apart from locked files. Then the install was successfull.
