thomas_murnane asked a question.
using property in Conditioin question.
Using Basic MSI:
I have 2 products that get delivered separately, say MainProduct and ProductB.
When the MainProduct is installed I set a registryKey of its install location.
When a user installs ProductB - I use a "System Search" and set it to a Property MPPATH.
For ProductB I use a setProperty Custom Action to set the INSTALLDIR = MPPATH with the condition being MPPATH (which will be null if the reg key does not exist)
I also use a setProperty to set a property MPINSTALLED using the same MPPATH - this property I use in the conditions for the features that can only be installed when the MainProduct is installed.
FeatureA
Level; Condition
0; NOT MPINSTALLED
1; MPINSTALLED
This all works fine: my problem is when the user changes the destination how do I unset the MPINSTALLED so the conditions for the features are still valid. Will setting MPINSTALLED=0 make this condition true: 'NOT MPINSTALLED'
Sorry so long - thanks,
Tom
Thanks,
Tom
Typically, one can fiddle with feature's install level, and evoke SetInstallLevel ControlEvent conditionally to control selected features for installation. AddLocal ControlEvent does something similar, but not as flexible.
