I want to show the vf page on the first installation of the managed package, or it can be the custom setting page should open up on installation, where the user will add all the custom settings on the first installation.
Is this possible, how can I do this?
Thanks in advance.
Go to Setup > Customize > Home > Custom Links
Create a new custom link to your VF page (eg /apex/ns__pageName)
Edit your package and specify the custom link
Now a [Configure] button will appear after install. Guide your users to click it.
