Third party filetype - MXLIFF can't work during automation

Hi,

In order to process Memosource file (mxliff), I installed below filetype, it works when work offline by Trados Studio.

But I created some automations by SDK of Trados Studio (Create Project, Convert, Analyze...), I use same sample files of MXLIFF for testing, it throw below exception although the filetype for MXLIFF already installed in my Trados Studio:

Source files can't be recognized/converted to Translatable Format by automation

I confirm my automation can work well with other format of files, eg: docx, html, xml, xlsx....

If this means Trados Studio SDK can't identify third party filetype?

Any suggestion will be much appreciated.
