Hi lynnharr
I think you are interpreting incorrectly - installing AccountRight SE 2026.5 isn't changing what version you subscribe to - it opens it depending on your subscription.
What I am saying is the AR SE 2016.5 will run your AccountRight Plus or your AccountRight Premier but still enable you to backup locally and/or run a local file.
Have a look at my screenshot - my AR subscription is AccountRight Plus - exactly like yours; however, my client subscription might be AR Premier - it will also open that.
The AR SE (server edition) is the software running it not the subscription.
Simply uninstall your local desktop version - download the AR SE 2026.5 - install - and voila you are up and running, that simple.
I have been running the SE version on my laptop for donkey years it has a lot more advantages and doesn't determine your monthly subscription.
