Thanks for the heads up Shawn.
I have just completed writing my C++ custom action although I am a .Net coder.
:)
I am using the Win API function GetTempPath() in my C++ CA to refer to the
%TEMP% directory and back in my WIX file, I am calling my support files as
[TempFolder]support.exe.
So will the %TEMP% location still be different in the cases highlighted by you?
Thanks,
Kiran

We use a similar approach of storing support files in a Binary table and
extracting them to %TEMP% during a custom action. However one thing we ran
into was that during the custom actions that wanted to use these files, %TEMP%
was not the same as where we extracted them to. This was due to each msiexec
process being run under a different session, which can be the case when
installing through terminal services (remote desktop), and on Wiindows Server
2003 and 2008.
As a work around we had the 'ExtractSupportFiles' custom action also write the
path it extracted to in the registry and referenced that in later custom
actions rather than %TEMP%.
Just something to watch out for.

Thanks again Blair! That's a very nice idea. Can you point me to some code or
site which can get me started?
Also I had another way (as explained in this link:
http://blog.deploymentengineering.com/2006/12/managed-code-can-access-msihandle_10.html
), using which a C++ CA will pass the MSI handle to the managed CA. In this
way the managed CA could access Binary table and execute the files. But this
means a lot of work as I need to host the CLR, then create the app domain, then
load and execute the assemblies. This indeed means a lot of work.
I liked you approach so I will give it a try.
Thanks again!
Kiran

What I have seen others use is a C++ DLL CustomAction that extracts all needed
files from the Binary table to the %TEMP% directory, leaving them there, and
the deferred CAs then use/consume those files using the TEMP environment
variable to find them. If you really shouldn't leave the files around, you
could add a rollback/commit CA that erases them from the %TEMP% folder.

Thanks Blair! I could not use a Binary table since the executables executing
in-turn depend on one or other files. Moreover these are console applications
so they will show a pop-up when the CA is executed. Also the CA's are deferred
actions. So I think a Binary table wouldn't come to my rescue.
Thanks,
Kiran

You could try using the Binary table instead of the File table to store the
support files. You would need to extract then yourself in a custom action, but
it could be the same custom action if that CA is not deferred.

Hi,
I am having an issue over here. I am using a custom action which uses some
support files. The action is required to run both in installation and
un-installation phases. But the support files needs to be removed after
installation. That means I will require these files again during
un-installation. How can I remove files after installation and again
install\remove them after un-installation? Any help would be appreciated.
Thanks,
Kiran
