Generic Fix for any 32-bit executable

The generic fix (use on any 32-bit executable) is this tool:  4GB Patch, found at NT Core.

But to use it you have to know, and be able to point the tool to, the exact file involved.

The 4GB Patcher by Daniel is a nifty little tool, that patches 32-bit (x86) executables (applications), to allow them to access 4GB (instead of only 2) of virtual memory on x64 platforms.

It will work for all 32-bit apps on 64-bit Windows systems, and is especially useful to improve performance of 32-bit games like Oblivion or Fallout 3.

WARNING: This may not work for all games or with Steam/OBSE/FOSE/NVSE. BACKUP YOUR EXECUTABLE BEFORE YOU TRY.

WARNING: Scan for viruses on any executable downloads, and always backup your Oblivion.exe and Oblivion.ini before trying patches of any kind.
