Drafting Error on AL Tools

Hi, i've installed Drafting 20 but every time I open it, it gives me back this message "C:\ProgramCAD\pDD_20\cdm\Enhancements.pe4\x64\Al Tools.dll wrong type".

Then it works but our company customization fails to load.

I've tried to uninstall and reinstall, to delete all the regedit keys, to copy the dll from another PC where this error does not appear. But nothing...

Can anyone help me?
