I am using Visual Studio 8 and Orca to create my installation package. With this, I am unable to implement Modify feature. package is installing fine. And Repair and Remove feature are working fine. But Modify is not working. I dont know what to do to add/remove feature(s) in Maintenance Installation. Any help is highly appreciated.

Use another Develomnet Environment, like WiX. Visua Studio use only one Feature, but you need more than one Feature to implement Add/Remove. Additional VS implement no Dialog to support this functionality.

I second you Andreas, Wix is awesome, and easy to learn for programmers. Try with the new Votive GUI as well. Well worth it!

Thanks alot for your replies.

Well, My package has three features (i've added these programmaticaly using installer DB functions), and I've added a dialog with three Check-boxes, every check-box corresponds to a feature. During Install, i can select any combination of features to install. and it works perfectly fine. But when i try to add a feature after first install (i.e. maintenance install) then no new feature(s) added, only the already installed features can be repaired or removed. I need to know, what I need to do to install a feature, not already installed, in Maintenance Install.

Thank you very much in advance

waiting ...

How does your check-box dialog select or unselect features? Usually you should use control events like AddLocal or Remove on the "Next" button of the dialog.

I have a property (for check or uncheck info) attached with every check-box. And I have a condition for each feature in the condition table, where, the level of a 'featuer' will be changed according to check-box property. And, as a feature with a level value higher than of INSTALLLEVEL value will not get installed, feature specific installation is performed. Unfortunately, this is not working for maintenance install.

Feature conditions are evaluated during CostFinalize, which usually si scheduled before your dialogs, so thoise conditions don't really work (they might work in some caseswhere the CostFinalize action is executed again in the Execute sequence, but you shouldn't rely on this).
The recommended method is using Control Events like AddLocal and Remove on the "Next" button of your checkbox dialog.
