set installer root drive programmatically

[RogerMont]

Hi Gang,

I'm creating a "master installer" in LV that will in turn install 3 existing apps by running the installers programmatically.  I don't know much about the MSI.  Is there a way to set the root directory programmatically by a command line argument or a text file setting or something?  As with every project, we're pressed for time.

I'll appreciate any help.

Thanks,

Roger

A starting point is to create one of the installers and run its setup.exe with:

setup.exe /?

I don't see a ROOTDIR override. The help says to search NI.com for "InstallerAutomation", which turns up this:

Not what you need, though.
