Hello,
I am currently using Free version of Advanced Installer but I have some questions as I think my team will be purchasing the Enterprise edition:
Can Advanced Installer check to see if a PC already has PostgreSQL installed and if so, uninstall it and reinstall the appropriate version as defined with AI's pre-requisites?

Re: Question regarding Enterprise functionality
Hi,
Advanced Installer doesn't have a PostgreSQL predefined prerequisite. However, you can try installing it using a post-install prerequisite or a custom action.
The main problem is that PostgreSQL uses an EXE bootstrapper which launches the main installer and then terminates. So your main installer doesn't know when the PostgreSQL installation is finished. This is why only a post-install prerequisite would work (the main installer won't wait for the prerequisite).
