Driver installation problem on a clean install

[aliceinchains]

After doing a clean windows 7 install, I go to install my drivers and they unzip and after I hit OK, it never prompts me to install, I have to go into the folder that I unzipped the driver in and hit the install from there. This has never been the case before as I have done a million xp installs.

Anyone know what could be the problem ?

I'm not sure it is a Windows 7 thing, but I never use Window's built in zip compatibility. But when I had, it usually has a check box at the end to open the contents, but it doesn't run anything automatically.
