What you can add more about the problem: "I am trying to install windows 7 setup on windows 8.1"
You must be logged in to post a comment.
The particular DLL file is the pat of the OS libraries, so when the dll is inaccessible or damaged it causes errors and keeps you from reinstalling applications and other features. The best way is to repair the file and associated registry entries.
That error is triggered by incompatible system components, in most cases, so you can either run a PC repair tool or optimizer and check for those misconfigured program settings or even corrupted registry entries automatically.
Fix 0xc000012f error manually by cleaning junk files, fixing other bigs or rolling back to older version of the oss/ updating WIndows entirely.
Good luck
