After a "Reload TMC/TMI" error "Source File <path> to deploy to target not found

When you perform a TMC/TMI reload, make sure you use the TMC file from the Publish directory: %TwinCAT3Dir%\CustomConfig\Modules\<MODULENAME>, not the file from the Build directory in folder <MODULENAME>_tct.

If you use the TMC file from the Build directory, TwinCAT cannot find the corresponding driver and you get the error message shown in the heading when you start TwinCAT.
