Recently, I discovered several issues with the process of mounting disk images and finding install packages, and I released two versions today. I am convinced that version 0.95 will work very fine and robust, but I want to apologize for the irritation this might have caused.
Please get your copy of QuickInstaller 0.95 and let me know when you still encounter unexpected error messages. Even when 0.95 is not listed here yet, the download link does always get you the latest version.
Also, be assured that no data loss or harm could happen with any version of QuickInstaller, the installation process was merely canceled for various but incorrect reasons.
Best regards,
