Ermm... I'd love to, but if you check this thread carefully, you'll find that I've already attempted to do so with absolutely no success. The installers always crash, and automatic updates don't work at all. My Windows XP installation has a lot of software installed and customizations, so re-installing it is pretty much out of the question, as it would take far too long to reinstall everything.
I'd love to provide the SetupDbg.log file, as I'm sure it would help solve this dilemma, but I don't quite understand where the file is saved or where I should add the switch that enables the generation of that particular log. I've included the Setup.ini file for you guys to take a look at.
