Please refer to this:

Graph3D is an app. You will need to duplicate the Advanced Graphing app and rename it Graph3D. If the main procedure as described on the link doesn't work, there are two alternative methods of installation listed.

"The programs with i send primecom i dont see "hpprgm"."

hpprgrm is the extension of HP Prime Programs, and won't be seen in the Program Library on the calculator (or emulator). You just need the program name to run it.

Hope this helps,
