Because 8.2.5 is the most recent version that HP will give me via the HP website.
I want to use .7, I just can't get ahold of it. This may be fixed soon as I've been harassing them about my licensing not being applied properly.
I just figured out my problem today. v8.2.5 at least, does not like Generation 2 Hyper-V VMs, once I deleted the instance and rebuilt it as Generation 1, things have been working as expected, though I haven't brought it up to production level yet.
