Hi,
I have this scenario :
I have released a version of our product (say, MainProduct Ver 1.0).
Now I want to create a patch to upgrade the already-installed version to version 1.1
In order to do so, I prepare a patch which will be distributed (msp file).
However, I want also to install a new 3rd-party product that is also a msi based installation, and I want to do so while the patch is being applied on the main release.
Can it be done ?
I did not find any infomration about that in the MSI SDK nor in the IS help.

Please advice.
:-)

Thanks,

Igal

From the Platform SDK help topic "Nested Installation Actions":
QUOTE
Developers should note the following warnings when authoring nested installations...
Patching and upgrading may not work with nested installations. ...

In other words: avoid nested installations, they simply don't work properly.

Stefan,
From an .msi then, you are saying we should not be calling any nested .msi installations, right?

Should sub-packages be done only through merge modules then?

thanks,

Daren

Yes, either merge modules, or from a bootstrapper exe.
