Presumably Session wraps the MSIHANDLE that you can't use from a deferred (non immediate) custom action. Whatever DTF offers in the way of CustomActionData is what you need for non-immediate custom actions.

I presume Session is a DTF thing but I don't use it. Sorry.

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

Post by Uwe ErnstHi Bharat,
your CustomAction probably throws an uncatched exception. Methods
capable of throwing exceptions should be executed from within a
try-catch block. There you can show the user your own error message or
create the missing directory. My experience is, that exceptions are not
transported from the c# method to the installer runtime, so you always
have to take care of possible exceptions.
Regards Uwe
Post by bharatjHello All,
I have written my first action script using C#. It has to create a text
under temp folder. If temp folder exists action script runs successfully
and
Post by bharatjWIX MSI works perfect. If temp folder doesnt exist action script returns
failure and Setup ends prematurely. It is not showing the intended
message
Post by bharatjlike " Unable to create file ".
