Installation fails because the drive or path could not be found
Question / Problem
I'm trying to install TreeSize, but the installer stops with a message "The drive or UNC path does not exist."
Answer / Solution
This can happen, if TreeSize has been installed on the system before, but on a partition that no longer exists.
To resolve this issue, please start the installer from a command line (or a Win+R-run prompt) with an additional parameter /DIR="C:\Program Files\JAM Software\TreeSize"
