[Fernando Navarro]

Hello, I need to know if a third-party application was installed, if the application aren't installed, then, I must launch the installer of the application, else, I must continue with the installation.

Does any people help me?

Thanks in advance (and I'm sorry for my english, but not is my mature language)

Hi Fernando,

I suggest using a Custom Action to attain your goal. Just check for the application (this depends on the actual application but usually a registry key is the criteria) and start the setup if necessary. You can read in the Help on how to create and use a custom action.
