i am hitting same issues. However the above recommendations did not work.

on windows 10
launching 17.0.416 command prompt says EnvControl: HOUDINI_USER+PREF_DIR missing __HVER__, ignored.

Then a pane comes up - the Houdini License administrator
saying: Error installing key: LICENSE Genereric Houdini-Master-NonCommercial 17.0 1 15-jan-2019 blah blah ….

Thats it. No houdini …

I cannot find any documentation on targetv and reading the popsolver notes there seems to be a definite science to how multiple attributes: drag, spindrag, targetv, airresist spinresist etc etc interact. There is no actual explanation of what targetv is?

Never mind resolved it:

//assign points to groups by rand:
int i = int(rand(@ptnum)*10);
string grp = sprintf(“group_%d”, i);
setpointgroup( geoself(), grp, @ptnum, 1, “set”);
