Windows 7?

Do not install the game to any directory under 'Program Files' or 'Program Files (x86)'

Why not? That is where I installed mine, by default, in the x86 folder, and it worked fine.

I downloaded SHIII from Direct2Drive.

I have a brand new machine with Windows 7 Pro 64bit, Core i7-930, Asus P6TSE motherboard, Nvidia GeForce 5500GT graphics.

I installed SHIII using the defaults (it went into Program Files (x86), and it ran fine, and I installed GWX3.0 using the defaults (it found Program Files x86).

Ran fine right out of the box.
