I don't think my install is a GFWL issue. I just installed "The Club" which requires GFWL from disc and it installed without problems. I'm trying to install Quantum of Solace from disc, it gets to a certain point in the install and hangs up and won't go any further.
I tried installing Quantum of Solace in an old Vista 32 bit PC and it installed without problems on that. Something in Win 7 that it doesn't like. My Win 7, 64 bit install is basically a "vanilla" install - I don't have any tweaks and very little extras installed. I have MS Securiity Essentials which doesn't interfere with installs.
