I have gone through the proper steps according to Blackberry's .pdf found on their web site, but the application does not install properly. I have created the setup.iss file via the /r switch, and copied it into the blackberry directory. My start.cmd line has not worked for any variation of the install. The only way I can get it to install silently on my test machine is by simply typing 'setup.exe /s'. Problem is, that doesn't work when I put that line into start.cmd. It just won't install. I remed out every other line, including the reboot at the end...but nothing happens. Here's my latest attempt: start /wait %systemdrive%\install\applications\blackberry\setup.exe /s FYI - I'm installing BB Desktop Mgr 3.6SP3 According to the pdf I have, the line to work should be (which does not work): setup.exe /s /f1"setup.iss" (no spaces btw 1 and ") Lastly, I just ran it one more time to be sure, and it does not install, but when I type setup.exe /s from the start-run menu, it installs silently...but won't do it by itself on the unattended install. (I deleted the command to remove the install directories)
