I have been using Apex SQL Diff for almost 20 years, but it looks like I won't make it to November to mark this achievement. Why? Simply because I had to reinstall my notebook and the latest license I got, back in 2017, can't be activated anymore. I wrote to support, but the only response I received was from someone in sales offering me their latest TOAD for SQL Server. I'm sure the software is great, but 95% of its features won't be useful to me.
When I purchased my latest license, the email stated, "ApexSQL licenses are perpetual. The expiration date represents the end of the support and upgrades contract, after which the product will continue to fully function." Fine for me, but that is simply not true: the product won't fully function because the activation process can't be completed.
