Patches for Heroes of Might & Magic IV
These patches are now available for download directly from our site. You no longer need to go to FilePlanet for them. Our server is quite fast, so download is fairly quick for broadband users, but please note that the files are large. If you use a dial-up connection, things could take a while, and you'd better grab a magazine and crack open a big pack of snacks.
Many people encounter a problem while patching, receiving an error message saying: "Old File not Found, but another file with the same name exists. No update was performed." If you encounter this error, the problem may be trying to patch with the incorrect language version. The list below shows the language version of your installed game in the Windows registry under the following registry key:
HKEY_LOCAL_MACHINE/SOFTWARE/New World Computing/Heroes of Might and Magic IV/1.0/
409 = US
809 = UK English
??? = Czech
40c = French
40f = German
??? = Hungarian
410 = Italian
40a = Spanish
??? = Russian
If you still encounter this problem and you have the correct patches, the error may be caused by modified .exe files (cracks=bad), or altered maps. In this case the best solution is to reinstall the game before patching. If you are comfortable with editing the registry, then uninstall your game, and delete the entire New World Computing key and all subkeys before reinstalling. Also delete any remaining Heroes IV game folders, making sure you back up your savegames and custom maps first.
