That did it, thanks! I only put in 1 hard drive this time so it didn't prompt me where I wanted to install it just installed it in the only available slot. which helped! Thank you!

I've gone through this loop several times where I install Oppm, try to run it, it says it isn't installed, try to install it, it says it's already installed. Is the command to run Oppm NOT just 'oppm' (no quotes) as I was under the impression? I've seen a good number of people asking this on tutorials but no answers. I don't know LUA in the slightest, I'm just following tutorials and what it says on the doccumentation website. I'm running Minecraft 1.7.10 with other mods.
