Hello everyone, so i've got some problem with program installing and launching.
Everytime i try to launch let's say Opera, Error appears, saying:
'"C:\Windows\system32\dhcpcsvc.DLL" is either not designed to run on windows or it contains an error.'

I Legit don't know what's the problem, i've tried to look for solution on internet, but nothing about dhcpcsvc.DLL, only other DLLs.

Help please? it's really annoying, and it happens with installation and some other Programs.

Awww, but I don't want to...
It started after I uninstalled some things I've counted as useless, so I guess that's the problem.
