Longhorn and IIS7

I'm trying to do some testing with the Longhorn and II7, which it seem to be running fine but somehow it will not execute anything that is .exe in my CGI directory(Scripts), it just wants to download them or save it. I know it must be something that needs to be activate to allow the cgi to execute but I cannot find anything.

I've activated all the roles possible and do see the ISAP and CGI restriction screen but there is nothing in there that tells me to allow the cgi.

In Windows 2003 server the IIS6 had an option under the web service extension where you could allow the Unkonwn cgi extensions.

If you have any suggestions it is more than welcome.

Thanks,
