Hello Steve,
Welcome! I am really not an expert for “Ultrasound” :wink: installation errors.

The only thing I know is that the installation can be tricky especially if you installed newer version before.

I am sure that one of the experts will try to help you soon. Meanwhile it would be great if you could provide more details about you installation.

Which OS are you using?
Which version of Ultraschall you are using?
Did you follow the easy to follow step by step instruction from step 1-4 even it is in German only ? :stuck_out_tongue_winking_eye:

https://ultraschall.fm/install/

Is it possible to post the whole error message?

I think if you add this information it will make much easier for others to help you.

Grüße,

Gero
