I have recently updated an XP PRO system to Nero 220.127.116.11. This gave difficulties with Nero Product Setup (18.104.22.168 - it decided to uninstall nero modules first but never reinstalled anything after), however with the help of one of the update.exe modules from Ahead I'm now on 22.214.171.124 as mentioned earlier. Only Nero Product Setup itself remained at 126.96.36.199; it indicates that an update is available, but updating aborts with: "cannot update MSI engine. Please update manually". Not being able to find any separate update for Nero Product Setup on the Ahead sites, I assumed Installshields MSI was out of date and updated all available versions (from 2 up to 11) to their latest versions (I was already on 11, by the way); version 12 seems to be out but I could not find any installable client package for that. Just to make sure I also updated MS installer to 3.1 (v2), but nothing helps. Any good ideas left?????
