--- Comment #16 from Dan Kegel dank@kegel.com 2011-10-28 08:29:07 CDT --- The progress bar finishes, then it goes back to the left for a pass of registering components, then it tries to start services... and on my windows 7, it put up an error dialog saying it could not start services. (There are a smattering of complaints about that on the web.) All this without a reboot prompt; maybe there would be one after it finished starting services, maybe not.
I don't know how much effort this app is worth, since the next version installs and works in wine, so I'm happy to abandon if you're not curious about it yourself.
