found this lurking around:

"Many of you may have problems with patching the Asian version of resident evil 4 (biohazard 4) 'cause the oficially patch refuses to install.

Here's a little guide I made

1 So first of all install Biohazard 4, full install

2 Then download the asian to european patch, and install it (not official, found via google)

3 After that, it will create a EXE-ORIGINALE folder in your game directory, with the original exe in it. Copy the original exe from that EXE-ORIGINALE folder to the main folder which will overwrite the one updated with the patch.

4 Go to your start menu->run->regedit, the go to HKEY_LOCAL_MACHINE\SOFTWARE\CAPCOM\biohazard 4
and rename it to HKEY_LOCAL_MACHINESOFTWARECAPCOMResident Evil 4

5 After that, use the EU patch and enjoy the updated game :)"



Nice one and if anyone had trouble installing the asian to euro patch , removing the game.exe and movie folder worked for me and the patch installed fine. Registery edit and put on the official patch and the graphics update is done... just need mouse aim now :)

Give it a whirl
