>In a pre-check routine to install a new aplication, I need to check whether the current user has local Admin level access. Does anyone have any idea what API, registry or WSH call(s) might provide this info? Is this OS dependent? (i.e. different for Win95 vs. XP)

Rick,

What are you using for your install? If you're using InstallShield's scripting products (e.g. Professional, Developer), then it's possible to use the SYSINFO structure variable to determine the OS and whether or not an admin is logged on.

Laterness,
