Setting registry value depending on installed feature

[michael@bitplane.com]

My Installer consists of two feature let's say "MainFeature" and "OptionalFeature". Now what I like to have is a registry value "IsOptionalFeatureInstalled" set to either true/false depending on whether "OptionalFeature" got installed or not.

This registry value should also be updated in case of uninstallation/repair/later installation of the feature "OptionalFeature".

How can I do this?

Many Thanks
Michael

Hi Michael and welcome to Advanced Installer forums,

Please note that you can create the related registry key in the Registry view. You can also take a look on the Add registry keys and values to your package article which may be useful to you.

Note that when you added the related registry, a new component has been added in the Organization page. Use the Go to component option from the context menu of the registry. Drag this component under the optional feature, as you can see below:

Hi Dan,

Many thanks for your quick replay.

I understand what you did and this should be sufficient to implement the desired behavior that we want in our application.

Now just out of curiosity: how would you set a specific value (true/false) to registry value "IsOptionalFeatureInstalled" depending on whether a feature is installed or not?

Best Regards,
Michael

You're welcome Michael,

Why don't you set the registry value as true right from the begining. If the registry exists, then the feature is installed. If the registry does not exist, then the feature was not installed.

Please let me know if that helped.

Best regards,
Dan

Hi Dan,

Yes, this is what we are doing now and working fine.

But still let's say the registry value is not a bool but stores some state like "ViewMode" as a string and the value depends on installed feature. How can you archive this?

Hi Michael,

You can set the related property using the Set Installer Property predefined custom action. You can condition its execution so it only be executed if the OptionalFeature was scheduled for installation e.g the condition is something like that:

Code: Select all

&OptionalFeature=3

For details, please take a look on the Edit Condition Dialog article with related information for hints and guidance. Also, please take a look on the Session.FeatureRequestState property article which may be useful to you.

Let me know if you have any questions.

Best regards,
Dan

Hello Marek and welcome to Advanced Installer forums,

Since you have 4 features, we may need 4 registry values (because we can not have the same name for a registry value): InstalledFeature1, InstalledFeature2, InstalledFeature3, InstalledFeature4.

These values can be added in "Registry" page, like this:

In the "Organization" page, you should have the 4 features, similar to this:

As you can see in the above screenshot, 4 new components were created for each of our registry values, i.e. InstalledFeature1, InstalledFeature2, InstalledFeature3, InstalledFeature4.

Simply drag and drop these components under its own feature:

Hope this helps.
