InstallShield 2008 Not registring DLLs

I have a problem that occurred only in some Win 7 Ultimate systems.
In my setup is suppose (among others) to copy files to the "Program Files" & "System32" directories.
The problem occurred when the setup try to copy files to the "System32" directory.
The install shield raise this error message box:
"Error 1926. Could not set file security for file C:\Windows\system32\, Error: 0. Verify that you have sufficient privileges to modify the security permissions for this file. "

I run the setup "As Administrator", run it when logged on as the user administrator, and still get this error every time I ran the setup.

As I write in the beginning this is only happens in some Windows 7, on other system it works fine.

I'm compiling the setup with InstallShield 2008 - Professional
