Norton Utilities 14.5.0.116b Windows 7 Home Premium will not install

The install program says that DeleteFile failed with errorcode 7

when trying to modify file c:\windows\system32\MSCOMCTL.OCX .

 

Question: Does NU 14.5 install on Windows 7 Home Premium (I think this is 64-bit, nt sure).

 

What is the workaround for this problem?

 

Thanks...  Bob
