I am currently using WixUI_Minimal dialog set, So, just like optional text (CA_Set_WIXUI_EXITDIALOGOPTIONALTEXT) can we add a button to the finish or exit dialog box on success scenario? I want to open a pdf file on the button click action.
Below is the code of how i am adding a custom text on finish dialog:
<UIRef Id="WixUI_Minimal" />
<CustomAction Id="CA_Set_WIXUI_EXITDIALOGOPTIONALTEXT" Property="WIXUI_EXITDIALOGOPTIONALTEXT" Value="Thank you for installing [ProductName]."/>
<InstallUISequence>
<Custom Action="CA_Set_WIXUI_EXITDIALOGOPTIONALTEXT" After="FindRelatedProducts">NOT Installed</Custom>
</InstallUISequence>
