Bben46 Complete Reinstall Procedure for Oblivion

Revised 7/8/09: Added fix for unable to reinstall by HemmyLane52
Revised 4/3/09, added recommendation for System Restore per suggestion by Qwaxalot
Revised 3/9/09: modified the disclaimer.

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. If you make any changes, please take responsibility for them and

document your changes so people won't blame me. As far as I know, no computer, game or

animals have ever been harmed by the indiscriminate use of this procedure.

It is also a good idea to create a system restore point before making any major changes to

anything in your computer. A system restore point will not bring back a deleted Oblivion, but

will save your existing Registry settings.

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.

If you have already deleted the game folders and now cannot install, Try this fix:

Thanks to:HemmyLane52 for this fix

1. Put the oblivion cd in the computer
2. Just exit out of the oblivion launcher that pops up
3. Go to my computer
4. Right click the disk drive the the cd is in (mine is ;E) and click on Explore
5. click on setup.exe
DONE!

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 move or 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.
