Vista - ZIP ERROR ACCESS is DENIED cannot create

Hi
I'm new to Vista and I'm not sure I am even in the right place on the forum.
My question is:
I have installed a music program called Sibelius which requires a fix to open. I have downloaded the fix, which is to replace a dll file, in a zip format when I try to extract the file to its required destination I get the message ' ERROR ACCESS is DENIED cannot create C:\Program\Sibelius\Sibelius5\portaudio_x86.dll'.

I assume I have been denied access by Vista even though I logged in as administrator.

Does anybody know how I can gain access.
Thanks

You may need to take ownership of the portaudio_x86.dll file.

Try method 2 here Take Ownership of file

Hi

I got round the problem another way by unzipping the file to the desktop and then dragging it into the Sibelius folder.
It seems rather stange that Vista allowed me to do this and not unzip straight to the folder.

Thanks for your reply I have printed Method 2 off for use in the future if required.
