How can I install a third party MSI using a custom action?

Question

I have a Visual FoxPro installer (exe) that I want to launch using a WiX custom action. However, I think the VFP installer is a wrapper for an MSI as I'm getting "Error 1500" which seems to denote I'm trying to run two installers at the same time.

How can I bootstrap this third party MSI from my own MSI?

I'm currently launching the VFP installer in InstallExecuteSequence. I tried to run it in InstallUiSequence, but I'm calling my own installer from a ShellExec, so it doesn't run the InstallUiSequence.

Any pointers would be much appreciated.

Answer 1

You really can't and it would be a bad idea if you try to "work around" it. If you really need this kind of functionality, use something like NISI to call the 3rd-party MSI and then call yours.

Answer 2

It is technically infeasible with the current version of MSI. Installing your additional MSI via a bootstrapper is the recommended way.

Answer 3

I've opened an MSI with Orca and saved it as a MSM (Merge Module) and added it to a Visual Studio setup project (not WiX sadly) before and it worked.

I'm pretty sure Orca comes with Visual Studio, but Google should give you good results to download it.

Give it a go in adding a MSM to your WiX project, and let us know what happens.
