newsposter, I ment that the causes were found and posted in those threads. For example the "missing setup.exe" is nothing more than removal of Manual Install component. Under 3 is the nhelper missing, I got that here and fixed for next version. Ut\Collector, seems to me that some of your hardware drivers is pulling those files during install? If it's missing during cd copy then attach your preset without any hotfixes or drivers in which you have confirmed missing files on one of the virtual machines...please RaGhul, I'm not THAT defensive or otherwise the app wouldn't be what it is. Anyone can post a bug report if it's confirmed by them...and if I manage to repeat it it will be fixed. There are 2-3 known common scenarios of the missing files, they include winnt.exe install and files above 8 letters...sp2 over sp1 integration...and corrupted CAB files before nlitement. Kiki Burgh, I prefer fixing, rather than sticking I fixed every common bug so far, why would this be any different. It's combination of other tools and that's kinda boring to test since I don't feel solely responsible for the incompatibilities.
