I am trying to copy and replace a file into the System32 folder.  I have given my account ownership of the folder, but still cannot copy and replace a file over to this folder!  Why is this?  This is the only user account on the machine.

Giving myself full permissions afterwards yields "error Applying Security" for each individual folder/file.
