The "Elder Scrolls IV: Oblivion" was released in 2006 and quickly became one of the best selling games of the year. "Oblivion" made over 1.7 million dollars in the first few weeks of its release. Besides being released in English, "Oblivion" was also released in Russian, Spanish, French and Portuguese in the form of a European edition. In order to change the language in "Oblivion," you must have the European edition installed and download an unofficial "mod" or "patch" to fix several bugs, including ones involved with selecting a language.
Go to The Elder Scrolls Nexus website (TesNexus.com) and left-click on the "Search" function at the top of the page. Type "Unofficial Oblivion Patch" in the search box and hit "Enter." Left-click on the "Unofficial Oblivion Patch" to navigate to its download page.
Download the "Unofficial Oblivion Patch" and save the folder to your desktop for easy access.
Open the "Unofficial Oblivion Patch" folder and double-click on the "Install Patch" executable file. This will patch your game up to the current version and fix several bugs associated with the European edition of "Oblivion."
Follow the prompts in the patch launcher and select the "Oblivion" game folder when asked where your game is installed to. This folder can be found in your "Program Files."
Finish the patch's prompts to install the updates. Double-click on the "Oblivion" shortcut to start your game.
Left-click on "Options" on the popup menu and then select the language you would like your game to be in. Left-click on "Done" to finish changing the language in "Oblivion."
Download and install the "Oblivion Mod Manager" program to more easily install and uninstall patches and other mods without deleting them from your system.
Make a backup of your "Oblivion" game files before applying any mods or patches to them. Corrupt mods or patches can ruin your install of the game.
