Silent uninstall instructions for ENVI & IDL on Windows

 

 

BACKGROUND:

Silent uninstallation is a way to uninstall ENVI or IDL software without the need to click through the user interface. This is beneficial to users that want to uninstall our software on many computers at once. A silent uninstall allows them to begin the uninstallation on each machine and walk away. 

*NOTE: Silent uninstallation is only possible on Windows platforms.*

INSTRUCTIONS:

First open a Command Prompt window, running as administrator.

Use the following command and flags to start the silent un-installation. 

\UNINSTALL_EXECUTABLE_DIR\unins000.exe /VERYSILENT /SUPPRESSMSGBOXES /NOCANCEL /FORCECLOSEAPPLICATIONS

The following is example syntax for a silent uninstallation of ENVI 5.4.1 from the standard installation directory:

C:\Program Files\Harris\ENVI54\uninsENVI541\unins000.exe /VERYSILENT /SUPPRESSMSGBOXES /NOCANCEL /FORCECLOSEAPPLICATIONS

For IDL 8.6.1 silent uninstallation, the command would be:

C:\Program Files\Harris\IDL86\uninsIDL861\unins000.exe /VERYSILENT /SUPPRESSMSGBOXES /NOCANCEL /FORCECLOSEAPPLICATIONS

where:

• SILENT tells the installer to display only the un-installation progress window, but not the un-installation wizard and background window.
• VERYSILENT prevents the un-installation progress window, un-installation wizard, and background window from displaying.
• SUPPRESSMSGBOXES tells the installer to suppress message windows. This flag only works when combined with SILENT or VERYSILENT.
• NOCANCEL prevents the user from cancelling the un-installation. It disables the Cancel button and ignores clicks on the Close button. This flag is also used in combination with SILENTor VERYSILENT.
• FORCECLOSEAPPLICATIONS tells the installer to force a close when closing applications.
