Hello Phil,
It may not be desirable, but we do have an older version of our software on the SA44/SA124 downloads page. It is version 2.18 of our software. It is not Spike but an older software package. This software does not have any GPU requirements and should be able to work on your PC. It’s on this page https://relatedcontentdemo.kinsta.cloud/support/downloads/sa44b-sa124b-downloads/ under the Legacy Software section.
I apologize for the inconvenience. If this is a new device and you do not have another computer to use the device on, please contact me at aj@signalhound.com.
Regards,
A.J.
