How do we add a new feature to one application that is already installed on the machine?

Question

Well, here's the case I've got.
 A long time ago, I have a deployed package that installs two features from one MSI file. 
 Now I need to deploy a new package containing one feature that was not available on the previous release, but I cannot uninstall the previous package, I need to add the new feature and maintain those from the older one.
 Can anyone advise?
 
 Thanks in advance,
 Luiz

Answer

You may create an upgrade package for the existing one.

Answer

Try using Reinstallmode property and check as below.Yes, that's right...re-install a feature which doesn't yet exist. Hmmm....LOL :)
 
 Sooraj is right. You need to create an upgrade for your product. If you're using Wise or InstallShield, this'll be a cinch.

Answer

But using the Upgrade, this will uninstall the previous application and install the new version, right ?
  
 I don't think this what he want. 
  
 How about creating a .msp ?

Answer

I've always found upgrade MSIs to be much more convienent in the long run than MSPs. I would recommend an upgrade MSI.

Answer

Hi,
 
 Thanks for your entries, but I managed to find another solution.
 I am executing the msi file using the following parameters: /QB! ADDLOCAL=FeatureName
 This adds the feature I want without changing the previous installation.
 
 Thanks for your help,
 Luiz

Answer

So now you have two separate products, effectively. What will you do for the next upgrade? Create yet another product? It's not a simple call, I agree, (as in, does a new feature require a new product or not?) but from what little you've told us, I'd say that the new product route was a mistake.

Hi,
 
 If things were on my hands alone I would do something about it, but my company has a very strict packages' structure. We're unable to modify published packages and many other restrictions, but thanks for yer help.

Answer

We're not talking about modifying the existing package. Have a browse on MSDN for details on what constitutes a 'product' and a 'package'. If you look up 'UpgradeCode', 'ProductCode' and'PackageCode', you should find plenty to keep you occupied.

I already said thanks for your help and support, there is no need to be rude.
