This guide shows how to hex-edit Origin to disable operating system check, which allows NFS Heat to download and install on Windows 7.
If this works for you, I'd appreciate if you bought me a coffee.
Check your Origin.exe version:
- For 10.5.66.38849, see revision 8
- For 10.5.64.37936, see revision 7
- For 10.5.63.37653, see revision 6
- For 10.5.60.37244, see revision 5
- For 10.5.57.35162, see revision 4
- For 10.5.56.33908, see revision 3
- For 10.5.55.33574, see revision 2
- For 10.5.52.32372, see revision 1
If the most recent version is missing, please check the comments; if nobody has commented about it yet, please let me know.
Alternatively, you can try the advanced patching guide that should work on any version, but the advanced guide is a lot more involved and there be dragons.
I recommend switching Origin to offline mode, because if the game needs an update, you will have to do this again.
Idk which part you're talking about.
