Re: [WiX-users] How to show custom error text on SetupCompleteError dialog when a deferred CA fails.

[Joel Budreau]

I think the standard is to have the deferred action make a call to 
MsiProcessMessage (not MessageBox), passing in a reference to the Error table 
(that way your displayed strings won’t live inside dll resource files).

 Hi,
 
 I have a deferred Custom action that fails in some scenarios. Since this
 custom action is responsible for installling some licensing libraries for
 my product hence I cannot continue installation if this CA fails.
 
 I want to show a custom error message to the user if this CA has failed the
 installation. To capture the failure from this CA I write a registry value
 signifying whether the CA was successful or not. But how do read this
 registry, set a property based on this CA and then use that property to
 show/hide my text on SetupCompleteError dialog.
 
 As soon as CA fails, rollback starts and then it does not execute any
 immediate custom actions. I cannot even use a roll back CA because it
 cannot set any property.
 
 Can someone please help and let me know if there is a way to do this other
 than throwing up a message box to the user?
 
 Thanks,

[WiX-users] How to show custom error text on SetupCompleteError dialog when a deferred CA fails.

Hi,
