We have a setup that needs to invoke another setup using InstallShield Express v 3.53.  We know that we can use a custom action to invoke a 'setup.exe', but how can we execute an MSI file directly.  VBScript maybe?

There are special Custom Actions for nested installations. Look for "Custom Action Type 7", "Custom Action Type 23", "Custom Action Type 39" and "Nested Installation Actions" in the windows installer documentation.

That information was helpful - it looks like MSI custom action 7 is what I am looking for but, the question remains, how do I invoke this using InstallShield Express v3.53?

Is it necessary to create a DLL that uses the MSI library to perform this custom action or what?  From within ISX I can only invoke a function in a DLL, an EXE, or VBScript.  How can I invoke MSI custom action 7?

Any help is greatly appreciated.

So, I believe that I found the answer in a post to the InstallShield ISX - General forum, specifically "You could create a Custom Action to launch Msiexec.exe and pass the path to the msi file as a parameter."

This means that using ISX 3.5x that one can use the EXE custom action, and specify:

Program:  [SystemFolder]/msiexec.exe
Parameter: /I <name>.msi

to invoke an MSI setup from within a setup.
