Hi Regin;
I am not sure if you realize this or not but SQLAnyWhere is no longer shipped with PowerBuilder in v2017 & higher. The agreement with SAP was only for PB & InfoMaker. However, you can download the free SA Developer version and if the PB 2017 installer sees that already installed, it will install the new demo database & then also align the PowerServer piece as well to that if you are also installing the PB 2017 Universal edition to that same demo DB.
In case you missed the SA link - please use this to install SA v17 first, before you begin with the PB 2017 installation.
HTH
