Can not restore any iPhone on my laptop or desktop!

[bulltproof]

I have quite a few iPhones that could use a jailbreak/retore.
The problem is I can't restore any of them OR jailbreak them.
I know my way around iPhones and PC's.

I have 4 laptops.
1 Fujitsu Core 2 Duo with Windows 7 Pro 32 bit.
2 Compaq Core 2 with Windows 7 Pro 32 bit
3 HP DV6 i3 Windows 7 Ultimate 64 bit
4 Lenovo i3 Windows 7 Ultimate 64 bit

I have 1 desktop
1 Gateway Core 2 Windows 7 Pro 32 bit

iTunes will ONLY install on the 32 bit machines.
I get "apple mobile device" error on the others

On every PC I have when I restore I get "the software for the iphone was corrupted"
------ EXCEPT the Compaq laptop
On every PC I have when I manually select the IPSW it hangs after starting the restore.
------ EXCEPT the Compaq laptop
On every PC I have sn0wbreeze gives me a CRC error when building the IPSW
------ EXCEPT the Compaq laptop


Any ideas?

Yes to both.
I've done fresh OS installs too. Used older iTunes, newest, and everything in between
