I mounted an .iso file and want to run the install file on it which is going fine. Then, at some point, the installer tries to make a new folder to install the program in. This, however, seems not to be possible. It just says failed to create folder.... I  think this is probably due to the installer not having root privileges. I tried running sudo ./install in which case it says:sudo: ./install: command not found.I also tried running gksu ./install in which case it asks for my password in a separate window and then proceeds to do nothing. I just see the terminal with nothing going on. Can anyone tell me how I can run the install as root?EDIT: Something weird may  be going on. When I do ls I see the correct contents of the mounted disk. Then when I start typing sudo inst and press tab to autocomplete I see a list of files that are not in the mounted disk. Perhaps in some deeperEDIT2: ls outputactivate.ini  help                  install_guide.pdf  readme.txtarchives      install               java               sysbin           installer_input.txt   license.txt        trademarks.txt    etc           InstallForMacOSX.app  patents.txt        version.txtEDIT3: its a christmas miracle, it works! I added the command exec to mount as exucutive and then did su - in the terminal and proceeded to install with no problems. Thanks so much everybody!
