Show custom message box on MSI Repair

Wed Jun 16, 2021 10:18 am


I want to show a custom message box on MSI Repair for following cases.

1.Maintenace Dialog Repair Button
2.When we right click installed MSI, It has Repair option.

The message box would be something like "Application is all ready installed" and further repair actions should be avoided. (i.e. It should not affect installed files)

Thanks & Best Regards,

Hello Vishal,

First of all, please accept my apologies for the delayed reply.

In order to achieve that, you can simply add a "Display message box" custom action under the "Install Execution Stage" and leave only the "Maintenance" option checked from under "Execution Stage Condition".

This should display the message box in both cases highlighted by you, as I think it has the same effect (i.e. right clicking on the MSI into repair and doing the repair from the Control Panel).
