Quote - I can't answer that question but what I can say is any modification of the executable would be in copyright violation, also I believe most ToS say you cannot modify or reverse engineer the code.

The 32-bit version doesn't appear to have that flag set in the header.

Setting the "Large Address Aware" flag in an EXEs header is not a copyright violation, there's also no guarantee that you won't run into problems (depends on how any libraries used cope).
