Take a look at this link below. Various Silent Parameters for Uninstalling Installshield Applications http://www.symantec.com/community/tip/2713...ld-applications Below is what I ended up using for my silent uninstall string. I had to generate the "uninstall.iss" file first by running an uninstall with the /r parameter. Just like you would to create the setup.iss for a silent install. RunDll32 C:\PROGRA~1\COMMON~1\INSTAL~1\PROFES~1\RunTime\11\00\Intel32\Ctor.dll,LaunchSetup "C:\Program Files\InstallShield Installation Information\{483AD544-F7DC-11D7-8B5E-00104BCAE605}\setup.exe" -l0x9 -removeonly -s -f1"c:\uninstall.iss" See this link for more info on creating setup.iss (i.e. uninstall.iss) files, etc. http://helpnet.acresso.com/robo/projects/H..._EXECmdLine.htm
