Abort the installation.If you need to change a property (like REBOOT) and set it to ReallySuppress in an MSI Package, go ahead reading this post. “IDABORT” is a constant which we can use to return to Windows Installer to indicate that “The ABORT button was pressed. * Make sure that this custom action is sequenced after custom action which sets the value of property ”CONDITION_A”.Īn external user interface (UI) handler can return any number of values to Windows Installer depending on the button type provided in the message type parameter the installer passes to the handler. * Use the property “CONDITION_A” which we have created, as a condition in “Install Exec Condition” of the Custom action. * In the Script Function field, enter the function name “ExitSetupFromVBS”. * In the VBScript Filename field, browse for this. * Write a script which sets the value of this property (true\false or 0\1) depending on conditions which decide the installation of MSI. * Create a custom property say “CONDITION_A”. Hence, we cannot use LaunchCondition table to meet the customer requirement of terminating the MSI installation silently (without showing any error message). If this launch condition fails then the installer will show with description that we have given in LaunchCondition table as shown in screenshot below. Screenshot below shows a dummy entry in LaunchCondition table. Please note that the description entry can not be set empty. If we use LaunchCondition table, then we have to give a description that will appear in message which is displayed when installation is terminated due to launch condition failure. If those conditions are satisfied, then installation should proceed, else installation should be terminated without showing any error message. It was requested to write a vb script(s) in such a way that during installation of MSI it will search for certain conditions. VB Script for exiting MSI installation from custom action without showing message.
