First, thank you very much for providing this information. Now Skyrim runs on my system without a hitch. Funny, as soon as I saw the topic "32 bit large memory access", I knew exactly what I had to do. Felt like slapping myself on the side of the head for not thinking to do this sooner. I do this stuff every day and I should have figured it out on my own. We run a 32 bit mapping application that is LAA and I had to do this to about 30 workstations shortly after we installed the software about 7 or 8 months ago. I have the "Important pior to installation" note from our vendor sitting on my desk at work. Thanks again for providing this info, something that Bethesda should have put into their install docs.
