EM CLIENT "FREE" VERSION UPGRADE TO "PRO" VERSION

I’M RUNNING EM CLIENT “FREE” VERSION, BUT WANT TO UPGRADE TO “PRO” VERSION. SHOULD I FIRST UNINSTALL THE FREE VERSION SO THERE IS NO CONFUSION ABOUT MIGRATING TO EM CLIENT FROM MOZZILA THUNDERBIRD? 

It is the exact same application. All you need to do once you have purchased the Pro License is deactivate the Free License and activate the Pro License. That is done in Menu > Help > License.

Yes that’s all you need to do - activate your Pro Lucence from your free version & that’s it. Also for you & others who raise queries, if you pay the upgrade licence fee you have free access to support who are very good & will answer all & any queries you may have. It’s definitely worth every penny
