I'm logged onto a Win7 computer with full domain admin rights - i'm trying to copy 7 dll's into the SYSWOW64 folder but I'm getting 'Access Denied' on 2 of the 7 i.e. the others copy without any problem. Any suggestions why those two might not copy? I can copy the two problem files to the Windows directory or System32 without issue, I'm puzzled why there's a problem with this specific two. Thanks.
