Niagara 4.9 introduced a new security feature called Module Signing, this requires all 3rd party software modules to be code signed with a matching certificate file from the developer.

You are now required to ensure that the matching certificate file is installed to the USER TRUST STORE of both the engineer’s Workbench (Workbench > Menu > Tools > Certificate Management > User Trust Store) and the target Host’s Certificate Management (Host > Platform > Certificate Management > User Trust Store).

Once the Certificate is installed to both of these places the JACE can be commissioned with the 3rd party software. It can then also be opened in the Workbench’s palette window for engieering use.
