Uninstalling a program before installing a new application

I have a question

I have an installer that calls a third party installer. This third party installer is now obsolete and conflicts with another third party installer. I want to modify AI to check and see if the obsolete program exists and uninstall that program before trying to install the new third party installer.

Is there any guide available that will help me with this. I'm currently using AI 8.0.1

Re: Uninstalling a program before installing a new applicati

Hello,

If the related obsolete application package is MSI-based then you can add its Upgrade Code in the "Upgrades" group from "Upgrades" page. If the application package is not MSI-based, then you should use a custom action in order to achieve what you want.

Also, you can take a look on our "Upgrade an older version of the package" article, which may be helpful for you.

Let us know if this helps, otherwise please give us more details about your scenario.

All the best,
Daniel
