Re: [WiX-users] Interpreting Return Codes of Executable Custom Action (type 2)

[Wilson, P. <Phi...@wo...>]

If the exit code returned by the program has no meaning, can you just make the custom action ignore the return code? 

I wouldn't use VBScript for several reasons, one of which is that it tends to run afoul of AV software. 

Deleting an installed file can be done without triggering repair later as long as the component guid is empty, see ComponentId topic:

Subject: [WiX-users] Interpreting Return Codes of Executable Custom Action (type 2)

Hello,

I have some questions regarding processing return codes of a custom action
that runs an executable.
I have an exe file that I want to execute as a part of the installation
process, but the complication is that the exit codes this file returns does
not satisfy the type 2 custom action return code requirement. That is, it
does not return 0 when it finishes successfully. And this executable is
3rd-party provided, so I can't do anything to the executable itself.

There were two solutions that I thought of. The first one was to save the
file in msi file table, install the file in some folder, and then to have a
vbscript to run the executable, process its return code, and if the file
completes successfully, make it return 0 to the msi installation session.

Another is to store the file in binary table, have a stub dll extract the
file from the database,
execute it, and then have it process the return code like I mentioned above.

My questions are

1) Does anyone have cleaner and easier solution?
2) For my first solution, would there be any way for me to delete the
executable after it is done running? I don't want to use dos commands to do
that, and I was hoping that there would be some sort of wix support for this
type of scenario.
3) Do you see any benefits to the second solution (use stub dll instead of
vbscript) compared to the first one?

Thanks!
