DTM could not be loaded

I installed Automation Studio 6 to test it, but I’m still using AS 4.12 for my projects.
Since I installed AS6 im always getting the error “The DTM could not be loaded successfully” on every build in AS4.12
It happens on different projects.

Has anybody experienced something similar and knows how to solve it?

Hi @c541797 Benjamin, welcome to the community!

I have both AS 4.12 and AS 6.0 installed and have not experienced this issue myself. However, a good first step for troubleshooting DTM issues is to try updating the DTM catalog. You can do this by going to Tools → Manage 3rd-Party Devices in Automation Studio, then clicking “Update DTM Catalog”.

You could also try re-importing the relevant DTM file(s) to see if that makes a difference.
