Version 1.9.3 is a free update for Version 1.x license holders.
NOTE: This version of SGS Prime COGO was developed and tested with firmware versions 2.1.14425 (2020 01 16) (G1) and 2.1.14433 (2020 01 21) (G2). Older firmware versions are not recommended as the software may not be functional on prior versions.

IMPORTANT: The Full installation option includes all the features for Lite, Standard and Professional while the Reduced installation option only includes the features for Lite and Standard and is less than 60% the size of the Full option. If your calculator displays a Device ID ending with -A1 or -C1 (aka G1), then the Reduced option is highly recommended. For calculators with a Device ID ending in -D1 (aka G2) and for virtual calculators on PC/Mac/iOS/Android either version will be fine, the Full option is required of course for the Professional features. In other words, at this time we don't recommend purchasing a Professional license if you have an older model HP Prime calculator (G1).
