Using version 0013, the installation failed at the stage of downloading files. For example, I know that the firefox.cmd starts running since the down/ffox folder is created. But nothing is actually downloaded so that the wihu window shows an error message about firefox not installed. The install.ini file is also created correctly since obviously firefox.cmd command is called by wihu. However, when manually running firefox.cmd file, the download and installation are able to finish without problem. Any insights about this problem?
