OR not showing up in OBMM

Followed all instructions and restarted PC.

Oblivion Reloaded is not a mod. You cannot install it via OBMM. Follow the install instructions.

Alenet kind of likes to cut through some BS questions by insisting to not installing via a mod manager. You can install via a mod manager, if you want. I always have and always will. What I will suggest is for you to drop OBMM--it's old and highly deprecated--and try out Wrye Bash for your mod management needs. My opinion is it's top dog for Oblivion. If nothing else, you need for it the Bashed Patch (which it's justification for using will depend on the size of you Load Order). So give Bash a try, you may like it.

The reason why i say to install OR manually is exactly to avoid problems with managers.
I developed OR and i know WHY. I dont want to explain everytime everything.

I know Alenet. Calm down, baby. I know you are trying to avoid the same retarded, repeated questions. All I'm saying from much experience is that the right mod manager can and will properly install OR. It's a fact. You (Alenet) just want to avoid noobs to a mod manger that are noobs to your mod asking inexperienced questions that tire you out. I'm with you there. Veteran players with large load orders should run a good mod manager. OR can and will be installed correctly by a good mod manager. For the record, the only mod manager I endorse for Oblivion is Wrye Bash (which is why I recommended it to the OP), but it's my opinion. Bash has been solid for me for quite a long time. The coders recently taking the helm have been solid (in my experience).

This is your site and your project. I'm not trying to call you out and make you look like you are making shit up. Fact is Bash will handle OR fine.
