@Surfer - your first file extracts correctly in my unofficial build (see previous post), as a 7-zip package. This as I changed 7-zip so it comes before Installexplorer. - your second file - confirmed, I have no idea why, though. @GrofLugi - I think you might be right, but the only way to find out is to contact the developers of the installation maker they used. Oh, by the way, I made a new build, 1.6.1.2. The only change was moving 7-zip before InstallExplorer. Surfer, please download the it, and retest. The link is: http://www.mediafire.com/?nmuzgtb32yy. Just extract it, and replace it as UniExtract.exe in the uniextract folder. Update: I forgot to update 7-zip. Please download 7-zip 9.14 from their website, and replace it in the uniextract bin directory.
