So in other words, you're trying to access the ir:u service without permissions, and then trying to use ir:u with an invalid handle (because you didn't get one due to access being denied). To be allowed to use it, you'll probably need to create an xml file for your 3dsx with contents like this (and also named the same, so for example: irtest.3dsx, and irtest.xml):
Code:
<targets selectable="true">
</targets>
..and then select a game or app that lets you use ir:u (probably Pokémon games; they feature IR trading, if I recall) when you try to run it from the HB launcher.
