Error 104 or 5017 means you are using the wrong CD to install
This error occurs when using the EQ7 CD once you’ve already installed EQStitch. The solution to this error is simple.
Just use the EQStitch CD to install instead of the EQ7 CD
You will need your EQ7 (or EQ7 Upgrade) license ID and password along with the EQStitch license ID and password.
The installation of EQStitch gives you all of EQ7 plus the additional features of EQStitch.
