The class LACSrsPrintDestinationSettings_Extension is now named SrsPrintDestinationSettings_LAC_Extension.

If errors related to LACSrsPrintDestinationSettings_Extension occur, some objects or models may not be checked in. Another possible problem is that not all models have been built.

Ensure the following new objects/dll files are added to TFS in case you are not just installing/deploying the AOT package:

  • LACSupport.dll.config

  • XmlDiffPatch.dll

  • XmlDiffPath.View.dll


The following is the complete list of objects that are not automatically added.

The version number should contain the intended version (such as in the following screenshot, 6.21) after either installing or deploying the AOT package.

Lasernet > Setup > Parameters

Add the AOT package

Either through LCS - Apply a deployable package to an environment

Or by installing a deployable package – Requires RDP access to environment

Different versions of Lasernet FO Connectorare supported with different versions of Lasernet. A setup for each newer version of Lasernet is required for any new installation and when upgrading from an older version of Lasernet.


It is best practice to refresh the Stylesheet after upgrading Lasernet FO Connector as this could help avoid potential issue(s).

Use the following Register selection classes, located in Lasernet > Setup > Backup parameters > Setup Default Selections, in case an error like the following is thrown when using Export, Import, or Copy across companies.

The newly introduced upgrade framework in Lasernet FO Connector 6.18 should manage but could fail when using a TFS/Dev build as this would require executing Microsoft.Dynamics.AX.Deployment.Setup.exe.



Error message


Please try to run ’Register selection-classes’ before processing.
