First, let me start by saying the MyChoice software is great (and great to work with). I had a sand-alone Visio 2016, and also have had Office 365 (personal) for about 1.5 years. Visio 2016 started acting a bit strange ... so I thought that I should just buy the latest version. After poking around, I found Visio 2021 through MyChoice at a very competitive price. Unfortunately, it wouldn't load. I called MyChoice the next day, and their customer service to me was SOOO AMAZING. I'm giving MyChoice such superlatives because they were totally aware of the potential issue(s) with 365 and gave me a refund. And because I NEED Visio (I'm a CPA/Internal Audit Consultant) as I'm drawing flow diagrams all the time), Microsoft is not getting into my pocket every month with a Visio Pro subscription. At least it's only an annual commitment - and I can cancel, then renew when my next consulting gig required it.
