hi, welcome to the forum
here's a link to your
reddit post, just so you don't get asked the same stuff three times
what I forgot to mention over there is that Nehrim will come to Steam next year -
mostly for better compatibility (because Steam doesn't really like it).
it will also include a new patch,
mostly performance related stuff (
current feature list).
BACK TO YOUR PROBLEM THOUGH
- you're using the Steam launcher to start "Oblivion", yes?
- where do you have Steam installed? the "
C:\Program Files" and similar tend to have some issues with rights
- you could try to let the Oblivion.exe (and maybe the Nehrim Launcher) use administrator rights
- you
maybe even could look into installing obse (similar tool to skse for Skyrim) and starting with that
(I don't know why that would work but stranger things happened)
if all fails you may have to reinstall (yes, following
the same steps you probably already did),
because as said, Steam is a bit odd with Nehrim
hope something of that works
