I just got the new version of OBSE and it says I need to upgrade to a higher version of Oblivion, how do I do this?

You probably need to have SI installed and oblivion.exe needs to be version 1.2.0416.

I doubt very much if you need SI installed, just the 1.2.0416 patch.

you just need the just the 1.2.0416 patch. previous version were compatiable with older version of oblivion, but the newest has dropped the compatiability.

To answer the real question, go over to the official site and download the proper official patch for your installation of Oblivion.
http://www.elderscrolls.com/downloads/updates_patches.htm

Make sure you get the proper language version and only use the SI one when you're using the Shivering Isles expansion as well.
Be warned though that patching after some time of using mods might be troublesome, because if any of the core files got altered, the installation will abort. Those are BSAs, shaders, fonts, ...and quite some others, so don't be surprised if it yells at you. In this case you'll unfortunately have to reinstall Oblivion and stick to the advised proper installation order for these and other things.

It works now (I installed SI), doesn't give me the message that I have to update but there's one small problem. When I launch OBSE it loads, then crashes instantly.

I suspect you mean that Oblivion itself crashes instantly, which is not an OBSE problem but an Oblivion problem, most likely related to a missing master file or some such.

When you launch OBSE, it opens a small DOS/commandline window, very briefly, which then closes and OBSE launches Oblivion itself. It's extremely unlikely that OBSE itself crashes before it launches the game, since all it does is inject some script functions that aren't even in play until they are called upon by a mod that needs them.

If you see the Bethesda Softworks logo (the game startup screen), even for a second, then OBSE is fine--- it's a problem with OB, which most probably has choked on a 'file not found where it was supposed to be'.

You might want to post your load order (preferably from Wrye Bash if you have it, secondarily from the OBMM if you have it).

When it starts up the window appears then it launches oblivion, the Bethesda logo itself doesn't appear it just goes to a black screen then it crashed to the desktop.

Suprisingly Better Cities doesn't work.

BUMP

When you start up Oblivion, are you using the regular OB launcher, or the OBSE starter?

I was using the regular Oblivion launcher before I got OBSE today, it worked before I reinstalled the game, but that was an older version this is version 1.7
Whenever I use the OBSE launcher as I said earlier it goes to oblivion then Oblivion crashes

Another BUMP

It's frowned upon to bump a thread unless at least 12 have passed, though it's more like 16 hours to be nice. You bumped after just over half an hour. The answer was already given to you anyway:



Basically, you've got a missing master. Use Wrye Bash to find out what it is, and make sure you install it. It's not a problem with OBSE.

The Oblivion.esm must be loaded first, not second ore anywhere else.

Edit: You have to use the OBSE Launcher, to get OBSE Mods to work properly or to work at all.

Not particularly surprising, considering your load order.

Aside from Oblivion.esm not being the very first item in your load order, which is most likely the main cause of your issue, I can see quite a number of items (related to Better Cities) that aren't as they should be:

Load order from OBMM

Better Cities Resource.esmOblivion.esm

Again, no mod of any stripe should ever be loading before Oblivion.esm. No exceptions, ever.

As far as I'm aware, all of these are patch files, requiring the original mod to operate correctly. You don't have any of the mods these patches require, so any and all of these might be your missing master right there.

Try moving Oblivion.esm to its rightful position as first and most fundamental mod, and removing all these files that require mods you don't have loaded, and see if that helps. If not, then we'll try again with a fine-toothed comb .

Thanks :tops:
It all works fine now
Just one question, is there any way to get rid of the exclamation marks?

Download and install the Better Cities Resources that contain the meshes (and textures) that those exclamation points are telling you are missing, maybe?

I have the resource files, I will reinstall it again. Bravil is the worst affected, purple buildings, exclamation marks everywhere :cold:

You have installed it incorrectly then. Make sure to read the readme before you try again, as you evidently didn't do so the first time. May I suggest you follow the exact steps of the readme, and maybe uses OBMM this time around. Because the readme is there for a good reason, and all of your BC problems could be avoided if you had followed it.
