I think the bundled software is a third-party RAW converter that Pentax has licenced, so it should treat Pentax RAW files the same as Nikon or Canon.
Which makes me wonder, are your RAW files set for DNG (Adobe's Digital Negative cross platform RAW format) or PEF (Pentax's proprietary RAW format)? That might have something to do with it, but I've never been clear on their differences. I use the DNG format mostly because I use Adobe's ACR.
