I couldn't run rhino 6 nor i could run grasshopper for rhino 5

I’m unable to run rhino6 .I downloaded it but i couldn’t run

Where did you download Rhino 6 from?


Do you have a Rhino license?

Are you aware that Grasshopper for Rhino 5 only works with Rhino 5?

Did you download the Evalation version of Rhino 6 or the Latest version or Rhino 6?

Did Rhino 6 install but not run after installing, or did it not install?

It installed but it didn’t work…i didn’t open

Rhino 5 is working but not rhino6(i installed but it’s not opening) and also i couldn’t install grasshopper5 for rhino 5
