Purpose
This article explains the cause of VMware Tools upgrade failure.
Cause
This issue occurs due to missing "C:\Windows\Temp\vmware-SYSTEM" folder in the guest OS of the target virtual machine, During the upgrade process the installer copies some binaries and installation files to the above location and fails to do so as the folder is missing.
Resolution
In order to resolve this, please verify if there are any automatic tasks or operations that delete folders under "C:\Windows\Temp\" within the guest OS.Please reboot the target virtual machine and confirm that the "C:\Windows\Temp\vmware-SYSTEM" folder is re-generated. Once the folder is available, perform the upgrade again.
