Not sure if this is the right forum for it, but it would be nice if the Windows installer remembered a custom install location, instead of defaulting to C:\Program Files(x86)\ every time.
You already have registry entries in HKEY_CURRENT_USER\Software\Plex, Inc. for Application Data and a custom Transcoding location.
Gerbil, this might better fit (if not already there) in the "Features and Bug Voting" section of the forum for us PlexPass users.
However, Ineed. I rarely install applications to my C drive any more, and usually limit the size of primary drive in my various OS environments I tinker with.
The variable most windows OSes see as Program Files can be changed of course upon a new setup, however, I've found that's usually more trouble than trying to remember to use the 'options' button when installing new versions of Plex.
