I tried it on a Cyrix 6X86 80Mhz system I have running Windows 95 OSR2 and it did the same thing minus the DirectX problem. I also tried using 98Lite on Windows 98 to install it without the IE and Media Player, and it did the same thing. I've lost some sleep over this doing software reinstalls and RRRs.

No other software that I have worked with has caused this problem. I've tried it on different hardware, different versions of Windows, and different configurations. QT5 is currently being boycotted by me, until they fix the shit code!
