Problems installing Defending the Reich on Vista

[D-Day_Dodger]

With my new found interest in Bomber Command I decided to resurrect my copy of Defending the Reich. I hadn't tried to play it since I upgraded(?) to Vista so I tried to install it and no go. I went to HPS' website and downloaded the 3 .dll files that were supposed to fix the problem. I tried to download these files into my Windows\System32 folder but every time I try this damn OS keeps preventing me.

It tells me I need the Administrators permission, but I thought I was the Administrator. I usually click OK and it goes ahead and copies the file, but not in this case. This dialog box comes up a lot and is most annoying. I recall that when I originally got my Vista system that this dialog box never came up, but when I re-installed vista myself, it does. Is there some way to get around this requirement or to remove it altogether? I'd be most grateful for any suggestions.

In the meantime, I just dug up my old pb copy of Guy Gibson's 'Enemy Coast Ahead' and will have to be satisfied with that until I get this problem licked.
