CANNOT FIX ISDONE.DLL PROBLEM FOR CODEX INSTALL, HELP!!!

[themercyshot]

I have tried multiple YouTube videos, reddit posts, changed ram settings, placed an ISDONE.DLL File and the UNARC.DLL file in sys32 and syswow, I am very very unsure what to do from this point on, I've been out this for 6 hours straight, if anyone can help me figure this out I would be so grateful!

You can manually place them by opening the C:\Windows\System32 and C:\Windows\SysWOW64 folders, then copying and pasting the files into these locations.

Have you tried uninstalling and then reinstalling the application? Also, consider checking your disk for errors by running chkdsk /f /r in Command Prompt. Hang in there!
