Installation steps for Tiberian Origins:
1. Download both OpenRA and Tiberian Origins. Make sure the version of the mod you download is compatible with the latest OpenRA release or playtest.
2. Install OpenRA
3. Go to your OpenRA folder - Default is C:\Program Files (x86)\OpenRA\ and extract the archive to the "mods" folder.
4. Create a shortcut of OpenRa.Game.exe (found in your OpenRA directory) on your desktop (or wherever you want it), then right-click the shortcut, and in the first dialog box where is says "Target", write Game.Mod=to right after OpenRA.Game.exe , AFTER the quotation marks and leave one space. It should look like this:
"C:\Program Files (x86)\OpenRA\OpenRA.Game.exe" Game.Mod=to
Click the Apply button, then the OK button.
Optional: If you want, you can change the shortcut's icon to one I made for the mod, by clicking the "Change Icon..." button. You can find an icon for the mod in the mod folder, OpenRA\Mods\to\to_icon.ico.
* If you can't find your openRA installation folder, right-click on the openRA icon on your desktop or start menu, click "Propreties", and then "Open File Location". This will open up your OpenRA folder. You can now go to the Mods folder and extract the archive there. If everything is done correctly, you should have a folder named "TO" inside the mods folder.
