[wix-users] Mysterious behavior in MSI

Thanks for the response.

I have Orca and InstEdIt! But I can’t tell where my customActions dll is

WinRAR shows the dlls inside the archive but nothing else – not my dll or
anything that would represent the installer tables/instructions.

This MSI only creates new databases.  all objects are only created, and a
few inserts of “setup” type data.

I’ve used the install logs to troubleshoot installs but I did not because
it might not be traceable there.

I do think that maybe an older copy of my dll stuffed is hiding in the


is there a way to start a new MSI from scratch? A commandline switch?

I am afraid that is not enough information to figure out what is going on.
Perhaps the old custom action DLL is still, somehow, used in your MSI. Are
you creating the database from scratch? Perhaps you are updating the
database and you don't have code to drop those tables.

Have you used Orca or Instedit to check the DLL that is actually embedded
in your MSI? Are you logging the actions taken? Such a log could let you
confirm that the tables are or are not getting created with the new
MSI/DLL. You could even log the entire XML content you are processing. That
could be a lot to log but it would let you verify that you are using the
content you intend to use. Are you starting with an empty database in your

I have a custom action in my msi that creates a database with tables and

packaged into the project as an embedded resource.

This has been working beautifully for some time now.

I recently changed the XML  - dropped a few tables for example, by editing
the XML.  I’ve looked it every way I can – I even opened the dll in
Resharper and verified that the XML does not contain those tables.

Still, when I run the installer, the tables are created - I just cant
figure out why.

Thanks in advance for any assistance.
