Hi,
as far as I know, the WmTransformationServices package is a package provided by Professional Services (same PSUtilities) and is not part of the regular installation image.
You should be able to find the latest version of this pacakge in the download section of this community.
It was developed for earlier versions of wM but still can be used on current versions.
In Designer, you can check, where this service is used in your code and replace it with the correspondent WmPublic, which is officially supported. This one has also the benefit, that you can specify the source and target formats.
Regards,
Holger
