Article link: How To Install Oblivion with Patches

This guide will help you install Oblivion, the official expansions and DLCs, the official and unofficial patches.

Game of the Year Edition

You do not need to apply any patches to the GOTY Edition because it is already 1.2.0416.

Windows Vista

If your operating system is Windows Vista, be sure to install Oblivion to someplace other than the default location under "C:Program Files" such as C:Oblivion or D:GamesOblivion

Install this way if you do not have Shivering Isles:

1. Install Oblivion 1.0
2. Install Official 1.1.511 Patch (only if you want the launcher to be fully functional)
3. Install Official 1.2.416 Patch
4. Install all Official Add-ons
5. Install the Unofficial Oblivion Patch (user-made mod)
6. Install the Unofficial Official Mods Patch (user-made mod)
7. Install the Official Construction Set 1.2.404

Install this way if you have Shivering Isles:

1. Install Oblivion 1.0
2. Install Official 1.1.511 Patch (only if you want the launcher to be fully functional)
3. Install Shivering Isles (which brings Oblivion to 1.2.201)
4. Install Official 1.2.0416 Shivering Isles Patch
5. Install Official Add-ons
6. Install the Unofficial Oblivion Patch (user-made mod)
7. Install the Unofficial Shivering Isles Patch (user-made mod)
8. Install the Unofficial Official Mods Patch (user-made mod)
9. Install the Official Construction Set 1.2.404

Load Order

There are a bunch of forum topics on this matter and they vary in implementation. Here is just one of the handy load order listings I found.

Patch Install Failures

If you get an error installing a patch at 8%, check for the following which might cause the patch to fail:

1. You must use the patch that is specific to your edition. Example: Direct2Drive editions must use Direct2Drive patches.
2. If you use OBMM or other tool for Archive Invalidation, be sure to disable this feature, remove BSA edits and restore to default.
3. If you use a "cracked" Oblivion.exe to bypass the CD-Check routine, be sure to restore your original EXE file or you will need to uninstall Oblivion, clean out the Oblivion folder and install from scratch.
4. If you installed Oblivion 1.0 and then got it patched to 1.2.0416 before installing Shivering Isles, it is possible that the installer will not work because it was expecting an older version of Oblivion. This would require uninstalling Oblivion and re-installing everything in the correct order.

Miscellaneous

Note about patch file size of 1.2.0416: The SI patch is smaller because the SI Install process updates Oblivion to 1.2.201, any patches after it would not need to be cumulative from Oblivion 1.0, just SI 1.2.201. If you have SI installed, the SI 1.2.416 patch contains only the fixes since 1.2.201.

If you cannot install the 1.2.0416 patch after installing Shivering Isles, try uninstalling Oblivion, then follow the same procedure except apply the 1.2.0416 patch before installing Shivering Isles.

You might want to add a comment/link about the D2D patches, though.

I see...

Galahaut, thanks for that information. I never knew Direct2Drive folks had an option. Now, if I can just get my hands on those files, I'd upload them here at TESNexus.

EDIT #1: Found one mirror location on the net. Now uploading to TESNexus.

EDIT #2: Direct2Drive versions now available on TESNexus and this article now updated to reflect this information.

EDIT #3: I believe that TESNexus is now the only source where you can download all versions and languages of all the Official patches and Construction Sets.

Hi... I have an issue which is always at 13% completed when it need to find a certain file... it is with all the other files and the notice mentions that it cannot find the "Old File" and I have NO idea on what that is! Please help me!

23Miestro, I have listed everything I've seen an know about troubleshooting the upgrade process...even though I have not actually experienced these problems.

I would suggest contacting Bethesda support. If / When you find out the solution, please return here and let us know how it was solved so we can update this knowledge base with your scenario.

Sorry I couldn't be more helpful,

Added the Construction Set as a line item since I think everyone should install this as part of the base install.
