If a separate data folder was used, the Message Exception Queue was not saved and was not available after a restart. 

The issue has been addressed and the Message Exception Queue will be saved now also, if a separate data folder is used. This is possible via the new properties Service Engine folder and Data folder. 

To benefit from this fix: 

• Update your zenon Software Platform to the latest build of zenon 12 or higher and update the MSI Interface AddIn in your project.
