The Customize Form button in the List Settings page lets you customize the list form using InfoPath 2010 (if InfoPath 2010 is installed on your computer and you are running SharePoint Server 2010 Enterprise). If this button is not working, your site is not trusted by your computer and that’s why it is not letting you open up the form in InfoPath. Check out the animated image below to see how you can add your site as a trusted site.

Thank you! This did the trick for me.
Thanks Asif for this quick fix.
Also, thank you for all the training material you have made available.

I salute you!
I’m humbled. Thanks Daniel.
I just installed Office 2016 and it removed my InfoPath 2013. I re-installed InfoPath 2013 and the ‘Customize Form’ button in my SharePoint 2010 environment stopped working. I checked my Trusted Sites and had to add it back. Thanks!!!
