Hi All, If I re-install a missing device driver (e.g. the BACNet driver was accidentally removed), will I run into any license issues? Or do you have any best-practice tips for when installing a module/driver to avoid issues? The 'module install' procedure in the manual seems pretty straightforward, so I don't anticipate any problems. As always, any help/info is greatly appreciated. \*IG version 8.1.32\* ---

Modules and licenses are not stored together. A license that includes a missing module will still show that module, and will be applied when the module is added again. Check the licensing/activation page of your gateway to see the module/version combinations included in your license. (Be sure to use the module version that matches your platform version.) ---

Great! Thank you!
