How To Install LATEST Paid Version of Blue Iris ?

[IPCamMan]

Hi everyone, I paid for Blue Iris, but my last update was back in June of 2021. I just re-installed Blue Iris from their download page, but it's the latest version. I input my serial key, and it accepted it, but now of course it says evaluation copy. HOW do I get back to the older version that was the last one I paid for ? thanks for any info !

When you go to the options dialog and click check for updates in the drop down can you not select a previous version?
