The other reason for this error message is that you previously installed one of the Shivering Isles beta patches. European and Australian discs have a different patch than North America game disc. On the PC, if you get an error message about 'Old file not found', first check that you downloaded the correct version of the patch (Shivering Isles and vanilla Oblivion have two different patches) or the correct English patch version. Bethesda's Shivering Isles FAQ provides additional information about SI-related issues. The FormID bug that is fixed by this patch affects all versions of Oblivion (even if Shivering Isles has not been installed) and therefore should be installed by all players.

The bottom left corner of the Video screen will read 'Version 1.2.1' if this FormID patch has been installed without this patch it will read 'Version 1.2' (if other previous patches have not been installed, the version may be missing completely or may read 'Version 1.1').įor PC users there are two distinct versions of this patch: one is specifically for users who have installed Shivering Isles and the other is for users who have not installed Shivering Isles (both versions are available for all localized versions of Oblivion/SI). To confirm that the FormID patch has been installed, Xbox 360 users should check the 'Video' screen under 'Options'.

Xbox 360 users will automatically be prompted to download the patch when they connect to Xbox Live. This is the final version of the FormID patch, and was released on. This patch is available for download for PC users and over Xbox Live for Xbox 360 users. Installing only disk 1 gives Oblivion version 1.1.425.

The 5th Anniversary Edition comes with the patch but this is applied only when disk 2 (Knights of the Nine and Shivering Isles) is installed.

Users that purchased Oblivion through Steam do not need to manually patch their copy of Oblivion, the latest patch is automatically incorporated into the game when it is downloaded, and subsequent patches are released through automatic updates.

Performance has also greatly been improved since the original version of Oblivion. Upgrading Oblivion to the latest patch is highly recommended, as many bugs and glitches are often fixed by the patches.
