I haven't actually used the Synchronizer, so I can't guarantee anything I say about it. But, I would take the Technical Specification document as the authority on what is supported, vs. the general summary info on the About page.
If you got to the technical spec page
https://hpln.hp.com/page/hp-synchronizer-alm-and-qc-technical-specifications
and click on the Downloads tab, and then expand the list for the version you want, then you should see the User Guide listed as one of the items available for download. That should provide you with the information you need about using the product.
