ComDirRoot configuration parameter (TDK)
Syntax (prefix with dash in a Generation Settings Scheme):
ComDirRoot=<path for ComDir>
Where <path for ComDir> specifies the absolute path of a folder in which the TDKComDir subfolder is created for storing the model SHK files.
The ComDirRoot folder needs to be specified before TDK loads a model, so use the ComDirRoot configuration parameter in the registry or in a Configuration Parameter File. After changing the ComDirRoot folder, all associated applications need to be restarted.
* 
The ComDirRoot configuration parameter also determines the folder in which the ComDir subfolder is created for storing ACS model SHM files.
ComDirRoot=C:\MyComDirRootFolder
