[finding_this_difficult]

I am building an installer that needs to call another MSI, but more specifically I need to calll it as a silent install. When I try the Custom Action for executing another MSI if I pass /qn it says another instance of MSIEXEC is already running and I need to wait until that install is complete. If I remove that condition it is no longer a silent install, but it does call and execute the installer. Anyone have any ideas why this is or how to get around thist?

Thanks,
A

Best option is to run the two setups one after the other by launching them from a custom written setup.exe.

Use a Custom Action type 7 or 23, which are run silently. Actually they're not completely silent, because they also update the progress bar (of the parent install).
BTW the use of nested installs is not always the best solution, you need to add extra logic on uninstall and repair. Patching the nested install is another issue.
