I have been running xampp successfully for years, and am now running 1.7.2 on XP. I recently decided I needed the Tomcat upgrade to do some Java servlet work, so downloaded the self-extracting version, pointed it at my xampp install directory, and clicked on install. All the files got installed, but then the cmd shell comes up and says "Sorry, but ... nothing to do" - somewhat disturbing. All the files are there, but when you try to install tomcat as a service, the bat file just says unknown service tomcat. So something didn't work with the self-extracting archive. I tried this twice just to make sure it was not a momentary glitch of some kind, but the behavior is consistent. Any idea what s going on here, and how to get past it?
