Wha?!? Tee-hee! This clearly shows that windoze knows exactly what it\'s doing!

However, it might even be (somewhat) right (happens sometimes). Try opening a dosbox (by selecting MS-DOS prompt in start->programs). If this really is an OS configuration problem, this should give the same error, because the pre-installer (run me first) is only a batch file, executed by DOS.
In the dosbox, type \"exit\" and then hit \"enter\" to close it again.
It seems to be W95 or W98 you\'re using?
