Enable/Disable feature at runtime

[prerak6962]

Hello,

In one of my application, I have a set of features. All the features are available for installation for "Full" version but only one is available for "Demo" version.
So, to achieve this, before the "ConfigureDlg", I have added one more dialog that asks for the type of installation using a radio group. The property name for this radio group is DEMO_INSTALL and the radio buttons have the following values:
- Full: 0
- Demo: 1
By default the value is set to 1.

In the organisations page, all the features are marked as "Installed" and I have the following condition in "Disabled if"

Code: Select all

DEMO_INSTALL="1"

Now, when the user selects "Demo", the "ConfigureDlg" displays only one feature which is what I want. But if he/she goes back and selects "Full", the "ConfigureDlg" is still not showing the rest of the features.

In one of the other user flows, if the user selects "Full" first, the "ConfigureDlg" shows all the features and upon going back and selecting "Demo", the "ConfigureDlg" now shows onle one feature. This is what I want.

As per my understanding from my previous post, a feature can be disabled in the dialogs but once it is disabled, it can not be enabled again because it can be enabled only before "Paths Resolution" stage.

So, is there a workaround or any other way to achieve what I am trying to do here? Or, I have to tell the user to relaunch the installer in case he selected "Demo" by mistake the first time.

Thank you.

Hello Prerak,

As my colleague Eusebiu explained, that is the implementation of Windows Installer.

So, is there a workaround or any other way to achieve what I am trying to do here?

Unfortunately, I am not aware of any way in which this can be worked around.

Or, I have to tell the user to relaunch the installer in case he selected "Demo" by mistake the first time.

I am afraid this is not possible either, as we can not condition the custom message spawn. For example, here we would need to spawn the message if user chose "Demo" and then pressed "Next" and then "Back". Such a condition is not achievable, I am afraid.

However, what is possible here is to simply make a double check. For instance, spawn a messagebox which asks the user once again if he wants to go with the chosen option. For instance, we can have two MessageBox custom actions, both spawned based on what the user has chosen.

Hope this helps somehow.

Best regards,
Catalin
