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.
I'm new to the party on this and have only just turned off Origin updates since your last fix. Unfortunately offline mode seems to only be of any use for launching games (in offline mode) - any updates and such requires the mandatory update. Awkward fuckers. lol
