Miro,
We typically add Templates to the “AutoCAD OEM CD” path in the Installer Wizard. Like for OEM 2024 we would drop them in a folder here: C:\Autodesk\ACAD2024ENUS\x64\aoem\PF\Root\UserDataCache\Template
Once they are in there then they will show up in the Installer Wizard under “Drawing Templates” and then you just add them like you see in the picture here:
Sometimes after adding them to the CD location you have to restart the Installer Wizard but they should show up and then when you build they should automatically be put in the Default Template folder. You might try that instead of the through modules.
