To understand why the module cannot register, you'll need to start nanoCAD under a debugger and send us the results.
What to do:
2. Start depends.exe, File - Open, choose ncad.exe from C:\Program Files\Nanosoft AS\nanoCAD x64 xx.x folder. It will take time to load.
3. Then Profile - Start Profiling.
Program arguments - /register
Select only the following options: Clear log, Log debug output messages, and Use full paths:
Then click OK.
Profiling will start, you will see a log at the bottom of the dialog. Please copy it to any text file and send it to us.
Also please send us a system information file.
