Sure you can entirely replace the distributed assets. It's called a total conversion and except for some adjustments in the ini and the level of complexity, there is nothing special about the retail content compared to a plugin you would make yourself. You can make a TC with just the basic tools you are already familiar with. All of The Elder Scrolls and Fallout games themselves are basically just TC's, running on customized versions of the Gamebryo engine. To be honest though, you're probably biting off more than you can chew if you are thinking about making one. Making a TC is a huge heap of work, even for something pretty tiny and you should have a firm grasp of how the engine works first. Just for fun, you could probably mash something together from retail and community assets without too much effort but then there could be copyright issues and you're basically talking about more of an overhaul compared to a TC. There are quite a few overhauls available already. These are basically TC's too, but instead of shipping all the files you need to build the overhaul and dealing with copyright issues, they provide instructions how to build it yourself.

If the compatibility mode is going to work, you should set it to Windows 7 or Windows 8 mode. ALSO enable Run As Administrator. Do that for BOTH the launcher and the game EXE. This is not a fix but a workaround so maybe you can play at least... You don't actually need the launcher. You can configure your settings in the ini itself, or use another tool like OBMM which has it's own settings menu to replace the launcher. Even if you can play though, I wouldn't be surprised if you have other issues. Oblivion was made for DirectX9 You can try downloading and installing that, if it will even run on Win10, I dunno.

Sounds like your computer can't read the disc. The disc might be dirty/scratched or your CD drive is dirty. Do other discs work or are most/all of them failing to read?

Ok, that is helpful info about the recent upgrade. Make sure you have tried deleting the ini and that it is the correct ini. Follow the instructions in this thread: https://forums.nexusmods.com/index.php?/topic/5736857-just-bought-oblivion-error-on-startup/&do=findComment&comment=51081842 If none of those troubleshooting steps work, then you should try rolling back the system to before the update and see if you can run the game. Windows 10 is pretty new compared to Oblivion, so it may be an issue with newer versions of DirectX not supporting the outdated version that Oblivion uses. If rolling back your system works, you can stop there if you want and either turn off automatic windows updates or figure out which exact update is the problem and ignore it in Windows Update manager. If it doesn't work, or if you want to try to fix the issue properly so you can update your system, then you probably need to install the older version of DIrectX that Oblivion needs.

I can try to help but you should create your own thread and send me a message with the link. Be sure to list your setup in your thread/post. Number of CPU cores and speedSystem MemoryGraphics card modelVideo MemoryOSWhat version of the game (GOTY/Deluxe, etc)

No problem. Glad it worked out for you on the first attempt. It's almost always that INI. It seems complicated but it's actually the correct way for games to be installed in Windows. Yes, you should reinstall the game into a different folder if you plan to mod. It's trivial to do, just takes a few minutes. The C:\Program Files*\ directories are windows system folders and are protected. It requires Administrator permission (which you likely are if you are the sole/primary user on Windows) to write into them. If you weren't an administrator, then you would get another popup asking you to run as administrator. Windows also checks that each executable application in there has been signed with a certificate, much like a secure website. Oblivion is old and is not signed. That is why you get the Unknown Publisher (unsigned application) warning. Installing to a different location avoids all that. For most games it's fine and correct to be installed in Program Files, but not if you're modding. As a rule, you should not be messing with anything in the protected system folders. If you want to mod the game, then it's a good idea to install it in a different location to avoid the permission issues and for your own convenience. When you start adding mods and stuff, you will be making changes to the installation folder regularly, so you'll have to deal with that popup quite a bit. Some of the tools that you will use might have trouble with the admin permissions as well. You also want to be able to easily organize your mods and such. Just configure an additional content library folder in Steam and reinstall Oblivion to the new location. Ideally, you should have your games on a fast drive, separate from the windows system drive (C:\). It can help improve gaming performance, basically ensures that you have full control of those files and helps to prevent you from potential disasters if you accidentally modify/delete the wrong thing in a system folder. If you don't have another hard disc, then you can create a C:\Games\SteamLibrary\ folder and have Steam install there instead of the default location in C:\Program Files\. Except for mods that are actually installed, you shouldn't store stuff in the game's install folder, so you should have another folder location to keep all your modding-related things. Oblivion would be installed to C:\Games\SteamLibrary\Oblivion\ and your extra modding stuff (downloads, tools,etc) can be organized in C:\Games\Modding\Oblivion\ for example. This way you can keep all your mod stuff close to the game install without polluting your C:\ with folders. If you get into modding the Bethesda games (and you totally should), things can get out of control fairly fast, so you want to be organized. To configure your new Steam Library folder: Open Steam, go to the Steam menu, click Settings, then in the Downloads section. Click the Steam Library Folders button. Click Add Library Folder. Browse to and select the new library location. If you want the new folder to be the default, then right-click on the new entry and select Make Default Folder. If you have other games installed already then leave the old library folder, otherwise you can delete it if you want. Reinstall Oblivion to the new location. Once you have the game moved to the new location, you should be able to run it without seeing the annoying security popup. Be warned that if you want to overhaul the game like you mentioned (and you totally should), then you are gonna get knee-deep in this stuff. Even if you only make cosmetic changes, some of the overhaul mods you can get make such a difference in the game it's night and day. Next, you can start modding. I can help you get pointed in the right direction on that too if you want, but u should probably start a different thread in the modding forum, since this one is a Technical Support thread and we solved your issue. If you want to create another thread, just private message me the link. BTW, you should tag this thread (update the title) as [sOLVED] now.

The Unknown publisher issue is a separate thing and as long as you accept, it shouldn't be a problem. Though, it's not desirable it's a fairly common issue with FO/ES games. You should move your steam library to a different Hard Drive location than the default to fix the permission issue. Get the game working first though. It sounds like the launcher is working for you, but the game itself is crashing. They are 2 separate programs. To be clear, you launch the game and get the settings menu where you click the Play button, then the screen goes black and crashes? Yes? You should know the locations where Oblivion is installed and where the configuration/save files are stored. The default install location for steam versions on Windows 10 is something like: (for 32bit steam) C:\Program Files\Steam\SteamApps\Common\Oblivion(for 64bit steam) C:\Program Files (x86)\Steam\SteamApps\Common\OblivionThe configuration and save files are located somewhere like: C:\Users\%USER%\Documents\My Games\OblivionFirst thing to try is to just delete the files in your config folder and then relaunch the game. Start by only deleting the Oblivion.ini and then launch. This will create a fresh INI file from the default. If that doesn't work, you may have some other files in there and you should try deleting those too. Still not working, then try this: https://steamcommunity.com/app/22330/discussions/0/535152511367016850/#c517142253877766086 Make sure to delete all the configuration files after uninstalling. Then reinstall with Steam Sync disabled. If you are able to make it work, then let me know and we'll see if you can't get rid of that Unknown Publisher issue and setup some mods if you like. If you can't get it working, then you probably need to tweak the INI and you should provide a bit more info before going further: - What is the exact location of the Oblivion install? - What is the exact location of the Oblivion config files and saved games? - Did you have Oblivion installed before on the same system? A Steam version? - Do you have other FO/ES games installed right now? Which ones? Steam or Retail?
