After downloading the .rar and .exe installation files for BI 4.1 SP04 Linux, we run the command
unrar x 51048295_part1.exe
as per the instructions on Service Marketplace. The files are all extracted to the current directory with the path as part of the file name, instead of creating folders. Looking at the help for unrar, that command should be correct. Any idea on how to get unrar to create the folder structure?
