When we try install Plex 73 in a VMWare Windows 10 system in a VDI environment the process gets interrupted. The install window just disappeared when prepared for installation.

Please create a new folder under C:\ or D:\ drive called "PlexTmp" and then edit the env variables TEMP and TMP( at system level and individual level) point to this C:\PlexTmp or D:\PlexTmp, then restart the Win10 and try install again.
