EF gave me very general instructions on installation and activation of Visio Pro 2021 and a product key that appears to be a legitimate Microsoft product key (five sets of five letters or/and numbers separated by hyphens). Before the purchase, I checked the reputation of Electronic First (EF) on Trustpilot (I realize that there are reports of fake reviews on Trustpilot) and. 8 on, which claims to be an authorized Microsoft reseller. I made a one-time purchase of a lifetime license of Microsoft Visio Professional 2021 as a desktop program/app on Dec. I hope that someone who is knowledgeable of the various ways of installing and activating Microsoft software can help me in this matter.
