How to seperate upgrade and first installation

[ahmetildirim]

Hi,
We are evaluating Advanced Installer for our product. It almost matched every one of our needs for the first installation phase with no problem. Before I ask my question, let me summarize what happens in the first installation phase.

• 1. Collect configuration information which required to run application
  2. Collect Sql Server connection information,
  3. Installation
  4. Apply configuration information to application (Finish Dialogs Stage)

When we upgrade version, Advanced Installer removes previous version and starts installing the new version from scratch. But we want skip 1. and 2. steps from first installation phase while upgrading. Because we don't need them even if it is a major upgrade.

So, how can we skip certain actions in upgrade mode?

Hello,

A major upgrade could be detected using "OLDPRODUCT" property. This contains a list with the Product Codes of the older versions of your installation package. This property is set only in a package which upgrades another package.

You could use the following condition :

Code: Select all

NOT OLDPRODUCTS

In order to condition the first two action you've mentioned. This will ensure the actions will only be executed if the installation is not a major upgrade.
