Launching MSI from MSI Setup

[Guest]

Hallo,

my application depends on others (libraries + a service), so I wrote a
custom installer action for my MSI setup project that tries to install all
dependencies. Unfortunately, one of them also uses a MSI setup. At that point
during the installation I get an error saying there's another installation in
progress at the moment and the second MSI file can't be executed.

Is it possible to launch other MSI packages from within a MSI setup (through
a custom installer action)? If not, what's the preferred way to solve such a
situation? Any help is highly appreciated, thank you very much in advance.

Usually such dependencies are inlcuded into you MSI as Merge Modules.
See if you can't get merge module versions of your dependencies.
If you use InstallShield, they have most common .NET stuff available as
merge modules.
