It's documented by the DoAction ControlEvent.
http://msdn2.microsoft.com/en-us/library/aa368322(VS.85).aspx
"Note that custom actions launched by a DoAction ControlEvent can send a
message with the Message Method, but cannot send a message with
MsiProcessMessage. On systems prior to Windows Server 2003, custom actions
launched by a DoAction ControlEvent cannot send messages with MsiProcessMessage
or Message Method. For more information, see Sending Messages to Windows
Installer Using MsiProcessMessage."
Go figure.... If you are using a ScriptCA it would work, but not for C++.
It would be nice if the effected versions of MSI were documented rather then a
reference to the operating system.
Of course it would be really nice if the bug would actually be fixed. I
guess it's another one of those `works as constructed` excuses from the MSI
team.

Subject: [WiX-users] Why doesn't logging from an immediate custom action work?
I have a custom action that I am running within the UI sequence (immediate,
user clicks on a button, custom action runs). Logging isnt working from it! I
can log without any problems when the same custom action runs deferred.
Its not the first time I see this. Any ideas? The code is straightforward
MsiHandle hRec(MsiCreateRecord(3));
MsiRecordSetString(hRec, 0, L"[1]: [2]");
MsiRecordSetString(hRec, 1, action.c_str());
MsiRecordSetString(hRec, 2, message.c_str());
MsiProcessMessage(_h, INSTALLMESSAGE(INSTALLMESSAGE_INFO), hRec);
Thx
dB.
