Hello,
Could it be that Stack- and Turbo-reg are not included in Fiji anymore?
I also could not find a corresponding update site.
Stackreg and Turboreg

These were moved to their own update site due to licensing issues. Please see this announcement:
I warmly recommend to subscribe to the Announcements category on the forum, by choosing the respective option at the top right on that category page 
Scripting menu?

Hello everyone. I’m just transitioning to Fiji from regular ImageJ and I have troubles downloading Turbo-reg. From the thread above I can see that the Stack- and Turbo-reg were moved to a different update site and are not a part of the Fiji. Does that mean that I need to download them separately to Fiji? I have been trying to add Turbo-reg Jar to Fiji but that didn’t help. Is there another plugin in Fiji which is similar to Turbo-reg or how can I upload Turbo-reg?

No, it simply means that you have to activate the respective update site (BIG-EPFL) in your installation.

Thank you very much! I have tried to run the updater but I do not get an option to select update sites. If I go Help > Update the updater just starts running and then it gives an error message

This error might have one of the following causes:
- you run Fiji from the opened disk image (
.dmg) file without first copyingFiji.appto your local disk, or - you run Fiji from a location where you don’t have full write permissions, e.g. the Applications folder on a Mac configured for multi-user access.
It should run fine if you copy Fiji.app e.g. to your Desktop and run it from there.
