Access denied on system32 folder in windows 8.1

I am trying to copy some dll files from server 2012 over to my windows 8.1 system32 folder so that I can register the dll's necessary to bring back the dial in tab in RSAT.  I copied the necessary files but when I try to paste those files in the system32 folder of my windows 8.1 computer I get an access denied error.

1. I already tried taking ownership - failed - still get access denied.
2. I tried doing this with the local administrator account. - failed - still get access denied.
3. I tried xcopy to copy the files over through a elevated command. - failed - still get access denied.

there has to be a way to grant permissions to the system32 folder. I just can't figure it out. Does anyone on here know how to do this. Open to all suggestions. this question is worth 500 points. thanks.

I was able to get it to work. I missed a step after taking ownership.

after you take ownership of the file or folder. you need to add your self permission. select a principal. add your account and select full control. I was then able to replace the files. I now have successfully added the dial in tab to RSAT.

Thanks for your suggestion John.

The easiest way for this (for me) is to make a neutral folder on the Windows 8 machine called c:\temp. Give "Everyone" permission to temp (and of course keep nothing important there).

Copy the files locally from System 32 to temp. Then move the files to your server. That should work just fine.

I am trying to copy the files to the windows 8.1 system32 folder... not the server.

Copy the files to c:\temp (permitted as above) and the copy locally to system32. I copy files there and into program files this way.

Selected my comment as the solution because this is what worked.

Actually the solution from John Hurst worked very well for me. For some reason even with full control rights you cannot copy file directly from network share to system32 folder. Copying to local temp folder and then copying to system32 works just fine.
