Windows 7: Failed MSI installation

Hi guys, I've been trying to install CS5 for the last few weeks or so and keep on failing due to several Microsoft Msi files not installing. Even when attempted to install manually. I've tried almost everything and spent about 4 hours on a remote desktop with an Adobe rep to try and solve it.

These are the MSI files that fail.


Microsoft_VC80_MFC_x86_x64
Microsoft_VC90_MCRT_x86
Microsoft_VC80_ATL_x86_x64
Microsoft_VC80_MFCLOC_x86_x64
Microsoft_VC90_MFC_x86
Microsoft_VC80_CRT_x86_x64
Microsoft_VC90_ATL_x86
Microsoft_VC90_MFC_x86_x64



They fail with the error code: 0x800736B3 when installed manually.



Oh and I'm installing it on Windows 7 Premium 64.
i7 720QM
ATI Mobility Radeon HD 5870 (1gb)
8gb Ram
2x500HDD

Try updating

BIOS,
video driver,
Sound driver,
disable AV and malware scaners

Be sure to have someone with expertise, in the area, work on BIOS.

Thanks Rich but rest assured these were the first things I did. Anyone else?
