To use OOO 1.32 Release Candidate 5 (RC5), you'll need two separate downloads to get everything working correctly. These are:

  1. OOO 1.3 Base Install (available from multiple sites -- roughly 400Mb)
  2. OOO 1.32 RC5 Upgrade (only on right now). It's available only as a manual install right now, but a scripted OMOD installer and EXE installer are coming soon.
  3. If you previously used any of the RC3 hotfix plugins, you should remove them after installing RC5. All of the RC3 hotfixes have been integrated into RC5. Also check the list of Known Issues With OOO 1.32 for help with any other potential problems.

If you're having trouble downloading the large base file, please read How do I avoid corrupt downloads.

The RC5 Upgrade can be installed over any existing OOO 1.3 installation. It doesn't matter whether you have any of the previous patches or not, but you must install the OOO 1.3 base package (see above) before adding the RC5 Upgrade, and you must update any existing savegames with Wrye Bash. You should also read the list of OOO Changes (updated for RC5). You've been warned.

Quick Install Summary

  1. Extract the 1.3 Base files to a temporary folder, then copy or move them into your \Oblivion\Data\ folder. When prompted to "Allow Overwrite?", click "Yes to All".
  2. Extract the 1.32 RC5 files to a temporary folder, then copy or move them into your \Oblivion\Data\ folder. When prompted to "Allow Overwrite?", click "Yes to All".
  3. Activate both the ESM and the ESP files (Oscuro's_Oblivion_Overhaul.esm and Oscuro's_Oblivion_Overhaul.esp). The Full Version and Lite Version are both included in the download. The Full Version is installed by default. If you want to use the Lite Version instead of the Full Version (default), then also copy the ESP file from the \Oscuro's Oblivion Overhaul\OOO-LITE\ folder, replacing the default Oscuro's_Oblivion_Overhaul.esp (which is the Full Version ESP).
  4. Activate any optional plugins you want to use. See Oscuro Install Options for a complete summary of the available choices in RC5. The option files can be found in the \Oscuro's Oblivion Overhaul\OOO-ADD-ONS\ folder.
  5. If you're planning to use an existing savegame, you'll need to update your savegame with Wrye Bash v118 or later. There are two parts to this step, so be sure to read though the next two steps carefully. 
  6. If you're upgrading from 1.3 or 1.31 to 1.32 for the first time, then you must alter the master dependency for OOO in your savegame to avoid losing any items you may have gained from previous versions (you only need to do this once when you first switch from 1.3 or 1.31 to 1.32, not when switching from a previous version of 1.32 to RC5). See "How do I update my savegame?" below for details on how to do this with Wrye Bash. Alternately, you can use the included OOOupsave.exe and follow the prompts.
  7. If you're adding OOO 1.32 to a savegame that previously did not use OOO (even if it was just created in the starter dungeon before adding OOO), then you'll need to use Wrye Bash to Update NPC Levels on your savegame.  This is also a good idea (but not required) when updating a 1.32 savegame to RC5. In Wrye Bash, select the Saves tab, right-click on a savegame, and select Update NPC Levels. All of the mods in your load order will be examined and the proper changes will be made to your savegame. Be sure to use Wrye Bash v118 or later when doing this.
  8. If you are upgrading a current savegame from OOO 1.3, you MUST take off any cape you may be wearing (or carrying) that you got from an NPC -- except guard capes -- and throw them away before you load your save with 1.32. If you are not sure where you got a cape, the safest route is to drop it into an empty container, save, install 1.32, then load and see if your cape is still in the container. If it's still there, then it should be safe to use. If you don't follow these instructions, you may get stuck with a cape that cannot be unequipped.
  9. If you are upgrading a current savegame from OOO 1.3, you'll need to enter a console command to enable the lockpicking restrictions. You need to type the following in the console (~):

    Set LapMinLock to 1

    After doing this, save the game and reload.

  10. If you use a Bashed Patch (a highly recommended feature of Wrye Bash), be sure to update it after upgrading to 1.32 RC5. Otherwise Oblivion may not launch. To do this, right-click the Bashed Patch in Wrye Bash and select Rebuild Patch (called Update Patch in older versions of Wrye Bash).
  11. Launch the game, load your save, then open the console (~) and execute the following commands:
    Set OOOFishSpawn to 0
    (This step is not necessary if you start a new game after loading RC5.)

Q. How do I update my savegame so I don't lose all my precious OOO stuff?

Note: This only applies if you've already been playing OOO 1.3 or 1.31 for a while and have accumulated a bunch of stuff you want to keep.

A. Run the OOOupsave.exe included with the RC53 download and follow the prompts, or use Wrye Bash. To use Wrye Bash, you must first download and install it. Once you get it working, launch Wrye Bash. Go to the saves tab. Select a savegame you want to fix (one made before the update). Click on it. Look in the lower-right corner at the masters list. Find Oscuro's_Oblivion_Overhaul.esp. Click inside the text and edit it to say Oscuro's_Oblivion_Overhaul.esm (i.e., just change the final "p" to "m"), or right-click it and select Change To, then browse to Oscuro's_Oblivion_Overhaul.esm and select it -- or simply change the ".esp" part of the filename to ".esm". The masters list will now be updated to swap Oscuro's_Oblivion_Overhaul.esp for Oscuro's_Oblivion_Overhaul.esm. Finally, you must click the Save button at the bottom of the masters list to save the change. Now, quit Wrye Bash, load Oblivion with that savegame and you're good to go.
