- I would check the installer versions on the target machines and see
if that is causing your problem. I've run into a couple of scenarios
where my dev machine had a newer version where it caused unexpected
behavior on the target machine, and at least once where the newer
version didn't work as expected and it worked on the target but not my
dev.
- After that, I would make sure that your dll has no dependencies, if
it has a manifest that it is configured correctly, and that it is
allowed to load. It's possible that you are linked against a debug dll
and your Custom Action dll is never loaded. Put a MessageBox("Hey",
MB_OK); at the top of your Custom Action to see if it is even running.

Hi,
I've been struggling with the following problem: my installer calls an
external dll by a custom action. This dll reads an xml file. I discovered
that in case of an error, the installer shows appropriate error message box
(I use the MsiProcessMessage method to inform installer about an error), but
only on the machine I develop the installer. I tried to run it on two other
laptops and there is nothing shown except the final FatalErrorDlg.
I was not sure if there is something wrong with the dll or with installer,
so I wrote a function in this dll which always returns error code and forces
MSI to log this error and show the message: and again the result was exactly
the same - just fine on my machine, but neither log entry nor message box
was shown on two other machines?
Anybody has any idea?
