Need help with my injector :(

yeah my windows is so dumb that whenever i try to run perx it says that i dont have the premission to open it and run it

You got a few options here.
-The injector file has been corrupted somehow so just reinstall.
-Get more theres a ton out there,
-Make your own. Im planning to release mines pretty soon. Its in the maplestory discussion hread. Spark Injector.

i cant even install my injector cant you read what i said

If the problem is with installing the inject, why not just try one which is an .exe and does not require installing.
If you've already tried PerX, you can give the Valkyrie injector a go as well. There's a long list of good injectors out there.
