Yes or No messagebox doesnt update property in MultipleInstancesDlg

[Chips]

Hello,

I am trying to add a Yes/No message box to the "Next" button on the MultipleInstancesDlg. When the user opts to add a new instance and clicks "Next," I want them to be prompted by a message box. If they select "Yes," the installation of the new instance should proceed; if they choose "No," it should return to the MultipleInstancesDlg.

However, I'm having trouble getting this to work, as the output property (BTN_PRESSED) of the custom action seems to be empty, regardless of whether the user clicks Yes or No. I suspect this issue arises because the MultipleInstancesDlg is part of the EXE Bootstrapper.

How can I achieve this if I can't use custom actions?

Best regards,

Hi Rafael,

I've tested this and it worked as expected for me. Are you sure that you set the custom action and conditions correctly on the "Next" button? They should look like in the image below:

Hello,
I believe somehow my multipleInstancesDlg has some underlying problem which is affecting it's behaviour (the dialog was bugged and it was fixed by support). I've sent my .aip to the support email.

Hi Rafael,

I'm sorry for my previous confusing answer, but I've tested this again and also talk to the development team and it seems that custom actions are not supported on the "MultipleInstances" dialog.

As a workaround, you can add an extra checkbox on that dialog that the user must check before proceeding with the installation.
