Can't save VI ...vi The VI already exists and you do not have permission to replace it.

I own the VI and have played with the permissions on the VI and folders it is in.  However, I am getting the NI message above as an administrator and owner of the file and can rename the VI from the Windows 8 file manager.

Is it in source code control and not checked out?  That'll do it every time.

Same here.  I only see this when the file on disk is read-only due to SCC.

Have you played with the attributes of the file?  This usually means the read only flag is set.  Be careful about unsetting it, though.  It was probably set for a reason.  Like the reasons mentioned above.
