Go to the releases at https://github.com/StrayaCoin/StrayaCoin-Core and download Strayacoin qt wallet version 2.0.0. If you don't have Windows you will have to compile on Mac or Linux.

I can make Linux binaries available if anyone needs one.  I found it was difficult to try and compile with the latest build tools on e.g. Ubuntu 23 or Debian 12.  I had to spin up a VM with an older version of Ubuntu 18.04 LTS Bionic.
