as far as I know this is the expected behavior - at least there's a MS article which describes the issue and the workarounds:
Let me know if this helps.
When you run RoyalTS 4.2.60801 as administrator by right clicking and selecting "run as administrator", it is unable to see mapped network drives.
We have a network share mapped that has connection documents in it, when you run as admin, Royals cannot see any network shares, therefore, unable to automatically open your documents. You have to manually search the network for that folder and re-load the document.
When you just double click and run it normally, it can see the mapped network drives just fine.
