Game won't launch when OBSE is installed

[Biff Stroker]

Whenever I try to launch the game with OBSE installed, it gets to the launcher but beyond that the game just doesn't launch. My mod manager is Wrye Bash, and I just launch the game by clicking the "play" button in the Steam menu. I've tried uninstalling my mods and running the game vanilla, which didn't work. However, I realized that when I deleted OBSE and ran the game WITH my mods installed, it started up and worked just fine. However, OBSE is required for some mods I have, so I need to find a fix for this so that I can actually play the game. I use OBSE version 0021 from the official website, but I've tried the mirror from the Nexus, which didn't work either. I've heard this could be caused by missing masters, but Wrye Bash indicates that all mods are in perfect working order. I've verified the game files, reinstalled the game, deleted the Oblivion folder in Documents, and none of it worked. The game is installed in C:\Games, so it's not a problem of being in Program Files. I also want to mention that I've played Oblivion on my computer before WITH OBSE, and it worked fine, so I'm at a loss for what to do.

Did you make any changes from before when it did work?

I tried to start a new game by uninstalling my mods and deleting my saves through Wrye Bash, but other than that I don't think I've done anything that would have caused this.

Well some of the mdos you had before might have overwritten files, which are now gone after you uninstalled the mods.
Usually when wanting to uninstall a bunch of mods and install others instead it's recommended to start over with a clean install. Anyway if you want to avoid all that work, which I can certainly understand I'd suggest you do this as test:
Backup your install do a different folder, then uninstall and manually make sure everything is deleted. After that to a fresh install and install only OBSE and the OBSE Tester and see if that works. If it does, then you know for sure something went wrong when replacing your mods.
Wyre Bash is often considered the best choice for all true experts, but it has more issues than it's fans admit. Too much can go wrong when merging mods and such. Personally I just used the TesModManager for my current install.
Either way good luck! I've been thinking about trying Morrowblivion after my current run through Oblivion and would love to hear that you got it to work and how.

The thing is, I DID start over with a clean install, and it still didn't work. I haven't tried using ONLY OBSE though, I'll give that a shot.

I see.
Yes try that anyway. Always install a few mods then testrun then add more, so that you can isolate the culprit if anything is the matter. If it works with just OBSE and the OBSE Tester I'd suggest adding all the other OBSE plugins like Silent Voice, etc those mods that come as .dll files and need to go into the OBSE folder next and run that before doing anything else. And if it does, backup that folder.
If you don't want the annoying scripted interruption playing while testing a configuration use this clean save: https://www.nexusmods.com/oblivion/mods/43403/
Puts you just at the exit of the sewers

Actually, Morroblivion starts you in the prison ship at Seyda Neen if you start a new game with it installed, so I was going to use that, but thank you anyway. I suppose I'll spend a few hours testing which mods work and which ones don't. Thank you for your help!

I got it to work! I reinstalled all of my mods one-by-one and I encountered no problems.

UPDATE: It worked one time and then broke again, without me doing ANYTHING in between. :/

That seriously doesn't make any sense.
That said I also have an issue with my current mod-heavy Oblivion install, namely that when I need to load a savegame where I was some areas removed from where I died the game crashes on my and I need to start afresh. Minor annoyance that I don't bother fixing since the game uses over 2GB memory whenever that happens, meaning I don't think it can be.
Now as for that's releveant to your issues: I might be that you are simply using too heavy a mod load for the engine to handle. Have you applied the 4GB patch to oblivion exe?
Alternatively it could be that some of the Oblivion mods you use, just don't play nicely with Morroblivion. If it's that I can't help you. I'd suggest making an account at the Morroblivion Forum and asking for help there.

just to personal imput here... my friend had almost the exact same issue with skyrim... she tried every fix known to man (and Daedra) and then realised it was her pc which was failing... bought a new one... no more issues (appart from a few script heavy mods)


ah but then skyrim uses 100% its own engine... just ignore me :P

[Biff Stroker]

Alright, I got it fixed for real this time. I had a rogue DLL in my OBSE folder, so I removed that and it started working.
