Step 2: Installing Heroes III data files
Step 2.a: Installing data files with GOG offline installer
If you bought HoMM3 on GOG, you can download the files directly from the browser and install them in the launcher. Select the .bin file first, then the .exe file. This may take a few seconds. Please be patient.
