Launching/Detecting Maintenance Install From Command Line...
I'm wondering what the command line would be to force a Modify install. The situation is this... we conditionally place some components, etc based on the presence of a third party app. What happens at times is that users update our software before they update the third party software. After they update the third party software, they can then run a Maintenance - Modify - "Change" install to place the new pieces.
On the Feature selection dialog box, when running through the UI, the said feature is now marked for installation and all works well.
Note: We support several versions of the third party product, so we can't utilize a launch condition because we have no idea what version they may be using/upgrading from.
I'm just wondering if one can run this maintenance install from the command line, or can you only execute a Repair (reinstall all (that were previously installed)) from cmd.
What compounds the problem is that we have another, native 64 bit installer that launches to do the same thing on that Architecture. What I was hoping to do was, from the placing install - detect that we are running a Modify by hashing out the command line. Set a public property indicating we are Modifying. Pass that to the widget that runs that fires the ancillary installer and run that install in maintenance modify mode as well.
Is there any way to
1) launch a modify from the command line that will place the features now seen as needed
2) hash out the command line to determine we are in fact in Maint/Mod mode. ?
