So older version is working? Make sure you have auto-update on Blue Iris turned off so that it doesn't automatically update and cause issues. Blue Iris Tools and @bp2008's update tool also keeps update files for you so you can easily revert back.Good call. I installed an older version and then was able to update.
If you already have BI installed then all you need is the update file to downgrade.I get the same error with the newest one.
I don’t see a download link for the full install of BI only the updates.
Does anyone have a link?
