indeed seems to be related to Wine's directory system, i have two partitions and one of them is set to be D:/, that partition is the one actually causing me problems, if i run an installer inside C:/ runs quite well, but if i do it from D:/ the problem present itself. Now, clean install and clean .wine prefix do nothing to solve the problem, if i look into wine configuration, two directories are present by default, "C:/ ../drive_c" and "Z: /", using an executable for browsing an installation directory expose the problem [Image: http://img52.imageshack.us/img52/6821/prbl.png ] this _BrowseProperty is set as a directory and trying to choice anything else causes a crash in the wine program, this in a very clean wine prefix
