Can InstallScript launch another msi?

[Mystique]

Can I launch another msi process (using 'LaunchAppAndWait' function) within a custom dialog created with InstallScript?

Any help is appreciated.

If it's pure InstallScript, yes, you can launch the command msiexec.exe /i package.msi (with appropriate properties and switches) to launch an MSI package.

Hi Robert,

I have one doubt.
Suppose if it is Basic MSI project then at that time is it possible to launch another msi

[RobertDickau]

Only one deferred Execute sequence can run at a time; some developers launch an MSI from the UI sequence or suchlike, but there are drawbacks (silent installations, privileges and rollback not working well, etc.).

Prerequisites or chained installers (see the sticky thread here about [thread=185662]chained packages[/thread]) are usually more desirable options.
