"Change TM ART Folder Configuration" tool does not move "teechart5.ocx"
The "Change TM ART Folder Configuration" tool is used to change the location where BMC TM ART Central saves its temporary files and log files.
All other files can be installed on another drive but teechart5.ocx is located in the Windows "AppData" folder: "<appdata>/bmcxx/teechart5.ocx"
This file is needed for the Chart Server to generate charts.
AppData is a Windows variable and the TM ART setup cannot change this variable.
If the AppData folder is configured to be on a different drive then this is where "teechart5.ocx" will be installed.
You will need to configure Windows to move the AppData location to a different drive before moving this file.
