The only issue with including all 3 runtimes in one package without downloading is that each of the downloads would be like 1.5GB, which doesn't bother me but I got like 10 people trying to get the sizes down as much as possible and even saying 500MB is too bloated, etc, which is why it downloads the runtimes. It's a 550MB runtime for each OS.
I can get the other issues fixed though, compression should be optional though and only happens when checking the box for that option. It's all stuff that works great when I test but random issue later. I'll get to it though.
