Summary

Set  “Always Overwrite“ to all files in a project using an InstallShield Automation Interface script.

Symptoms

In a project which contains a large amount of components and files, where files are frequently added and changed, setting Always Overwrite for each file manually is problematic and time consuming.

Resolution

It is possible to use InstallShield's Automation Interface functionality to automate this process.  The example below uses  VBScript code to set the "Always Overwrite" setting for all files so that the check box is checked.

You can run the script using a VBS Editor or you can run the script using “wscript.exe” or "cscript.exe" in an Administrator command prompt.

Path to wscript.exe “C:\Windows\System32>wscript.exe”

'Create project object for InstallShield 2021
Set pProject  = CreateObject("ISWiAuto27.ISWiProject")
 
'Open project
pProject.OpenProject "C:\InstallShield 2021 Projects\My Project Name-4.ism"

Set pComponent = pProject.ISWiComponents

Msgbox pComponent.Count

For Each pComponent in pProject.ISWiComponents

Set pFile = pComponent.ISWiFiles

MsgBox pFile.Count
