i understood about this much of what you just said... yup, that's about it. UPDATE to the latest XPlode. Do this first. recreate your XML for the new version. READ, it's pretty simple. Also, is PostInstall going to be at the root of your CD? Take THIS into consideration, since if it is, it won't get copied over so SYSTEMDRIVE ISN"T THE APPROPRIATE VARIABLE. When running XPlode, add this line at the end of your execution string /log:%systemdrive%\xplode.logsee what errors come up.
