You MUST use the original Oblivion disk to uninstall or it will cause problems when you try to reinstall.

 

Bben46 Complete Reinstall Procedure for Oblivion

 

I would appreciate any feedback on this as it is something I expect to post often and I hate to give bogus or useless information.

 

Even though this has worked for many people, You get a disclaimer, just like the big software companies use to limit liability.

This is usually a last resort and your game is already trashed. I cannot be responsible for any damage you manage to do to your game when trying this. You are free to

 

use this procedure and post it as you see fit. As far as I know, no computer, game or animals have ever been harmed by the indiscriminate use of theis procedure.

 

When you uninstall Oblivion it doesn't really uninstall everything. Then when you start adding mods before you have started the game, some things may not get

 

initialized properly. Here is my recommended procedure for uninstalling and reinstalling.

 

The game uninstaller does not remove your mods, save games or Oblivion.ini or the entries that the original installation of Oblivion placed in your Windows registry. It

 

also does not remove helper programs such as OBSE, OBMM, Wrye Bash, The construction set or any other programs you have installed in the \Oblivion folder or the

 

save game folder.

 

DO NOT delete the Oblivion.exe or the Oblivion folder as that will cause problems when you try to uninstall or reinstall - allow the game uninstaller to take care of it.

 

 

Uninstalling Oblivion - you gotta remove it completely before you can reinstall it.

 

DO NOT DELETE THE GAME FOLDERS YET! This is very important.If you delete them,it causes problems later.

 

My instructions assume you are using Windows XP and have installed Oblivion into the default location. If you are using Vista or Linux, the file locations may be

 

different, however, the procedure will be the same.

 

For a full reinstall, first you can try to preserve your mods and save games. I recommend that you save them in a new folder with a new name. Create the new folder in

 

C:\Backup_Oblivion - or any other name you will remember, just as long as it is not in the programs folder.

 

Then copy the data folder where your mods are to the new folder - do not erase them, copy them. And in the new folder, rename the \data folder to \olddata. Then copy

 

and rename the folder that has your saved games and Oblivion.ini, C:\documents and settings\your user name\my documents\My Games\oblivion to something like \My

 

games\Old Oblivion - this saves your saved games and the oblivion.ini file.

 

 

Then, using the original CD, NOT the Launcher on your Hard drive. Select uninstall.

 

After it completes the uninstall, reboot your computer - this is important as it allows Windows to remove some references to the original Oblivion.

 

This would be the time to erase all of the helper programs you have in the \Oblivion folder. Such as OBMM, OBSE and some others. The simplest way is to delete the

 

folder completely. The new install will re create the folder for you along with a fresh oblivion.ini and when you start the game and make a save, a new save folder and

 

new \data folder.

 

Now you can delete the game folders if you want to do a complete fresh reinstall. Your original saved games & mods are backed up if you want to try to resurrect them

 

later.

 

Now to remove the registry entries that were left behind. If all else fails, this usually works to resurrect your game.

 

I do not recommend manually editing the registry unless you know what you are doing. A mistake here could make your entire computer unusable.

 

There are several good programs for removing left behind entries. The one I use is ccleaner. Be sure to reboot before using it, and again after. It is free and available

 

here:

This would also be a good time to do a file clean up. Run the built in Windows 'Disk Cleanup' routine. If you uses the ccleaner, most of this has already been done, but

 

it won't hurt to do it anyway.

 

Now that everything is cleaned up, do a full defrag on your hard drive to leave a large uncluttered area to reinstall to. This prevents your game from installing in a

 

fragmented way, with parts scattered all over the drive. It also will speed up the install a little. It takes a while, but may speed up your game as well as the rest of your

 

computer.

 

At this point Oblivion should not exist on your computer.

 

 

Now to Reinstall.

 

Again using the original CD, install Oblivion.

 

NOTE: If you are using Vista, DO NOT install to the default directory. Instead make a new directory I recommend C:\Games. Install Oblivion there to avoid the hassle

 

with Vista UAC blocking mods.

 

Before adding any mods, patches, helper programs, Shivering Isles or anything else, start the game and make a save. This initializes some stuff that needs to be

 

initialized.

 

If you are using the Game of the Year version of Oblivion you should not need any patches, skip the patching part.

 

Now, If you DO NOT use Shivering Isles, patch the game using ONLY the latest Oblivion patch. All of the stuff from the earlier patches is included.

 

Be sure you use the proper language patch. If you use the wrong one it may work, but with a strange mixture of languages. (Germanglish?) Or it may crash.

 

NOTE: there are two English Patches UK & US and they are different. (Some people actually think we speak the same language) Use the one that matches your original

 

disk.

 

If you use Shivering Isles, Install it now. DO NOT install the Oblivion patch. Install Shivering Isles, then ONLY the latest Shivering Isles patch. All of the updates for

 

Oblivion are included. There is only one Shivering Isles patch for both US & UK English (Maybe sometimes we do speak the same language.)

 

Now, again start the game, make sure it looks right, move around a little to test it, and make a save. Test to be sure everything is working right (No purple objects or

 

yellow blocks)

 

Before adding any mods, back up both your \data folder and the save game folder. Copy them, don't move or rename them, to a different folder - such as

 

\Bethesda\Clean Oblivion\data and \Bethesda\clean Oblivion\saves. Note that this is a different folder than the one used for your old data and saves.

 

Note, Your Oblivion.ini file is in the same folder, but separate from, the save game folder.

 

Now, if you want to try to run with your old mods, first rename the original folders. The \data folder to \newdata and the \oldata back to \data. this restores all of your

 

mods. You should now have 2 data folders \data, and \newdata in your \oblivion folder

 

To restore your original saves and ini file, rename the new My Games\Oblivion to something like \New Oblivion. and the \Old oblivion to \oblivion - this restores all of

 

your saved games and your original Oblivion.ini file.

 

DO NOT erase the files you renamed. These are your backup files in case the original mods do not work or give you the same problem.

 

If you have the same problem, it is most likely caused by a mod. However, you now have a clean install to fall back on. You can You can COPY (NOT move or rename)

 

the backup files back to what they were and be back to your clean install without having to reinstall again.

 

Sounds like lots of work, but you will have a clean install and a back up clean install when you are finished.

This problem can also be caused by a missing ‘_setup.dll’ file in the appropriate Installshield folder for Oblivion.

 

Check “C:\Program Files\InstallShield Installation Information\{35CB6715-41F8-4F99-8881-6FC75BF054B0}” for the file _setup.dll, which should be 156kB in size.

 

If it is not there, and you’re lucky enough to have installed one of the add-on packs for Oblivion (such as Horse Armor, Wizard’s Tower, etc), you’ll also find their folders here as well (I found which were which by viewing the contents of the setup.ini files in each folder). They all use the same _setup.dll, 156kB in size. Simply copy one of these back into the folder listed above, and the uninstall will then proceed normally.
