MsiProcessMessage() is probably what you're looking for. I don't know what the DTF equivalent is. http://msdn.microsoft.com/en-us/library/aa370354%28v=vs.85%29.aspx

Subject: Re: [WiX-users] Setup wizard ended prematurely because of an error Hello Uwe, Thanks for the info. This is my action script code: *public class CustomActions { [CustomAction] public static ActionResult MySimpleAction(Session session) { try { File.AppendAllText(@"c:\tmp\time.txt", ";Installation: " + DateTime.Now.ToString()); } catch (Exception) { return ActionResult.Failure; } return ActionResult.Success; } }*The above custom script is creating a text file under tmp folder. It works fine when tmp folder exists without error. But when I remove temp folder to check the error message to display, setup is ending prematurely. Following are my CustomAction and Install Sequence * <CustomAction Id="myActionId" BinaryKey="myAction" DllEntry="MySimpleAction" Execute="deferred" Return="check" /> <InstallExecuteSequence> <Custom Action="myActionId" After="InstallInitialize"></Custom> </InstallExecuteSequence>* Thanks & Regards, Bharat Jasti Team IT Rainbow Design Services On Tue, Apr 12, 2011 at 5:08 AM, Uwe Ernst <uwe.er...@gmail.com> wrote: > Hi Bharat, > > your CustomAction probably throws an uncatched exception.
