Unable to copy some DLL's to SYSWOW64

hi,
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.

Are the DLL's true 64-bit DLL's?  Have you check the permission on the files to make sure Read Only has not been set?

If some DLL's copy and a couple do not, I would look to compatibility and permissions.

take ownership of the folder The normal permissions normally don't allow you to write to that folder.  Are those dll's in use? perhaps if you unregister them, reboot and then copy over the new ones and then register them it will work.
