A Windows wizard and installer

We need a one file executable that first acts as a wizard and then as a program installer. The wizard part will run some network nets on the user computer (ping times, traceroute, connectivity check) and report results. The installer part will just install a program (copy files, config, etc). The installed program must be uninstallable from the control panel as usual. The program must work in Windows XP SP2+, Vista and 7. It can't depend on anything that isn't there in a typical Windows system and that it can't include itself (you can statically link with any library but you can't expect the install PC to already have any runtime).
