Install problem

VisualARQ rhino has been installed that can be seen on rhino screen, then visualARQ grasshopper has been installed but it cannot be seen on grasshopper screen.

@kenang,
Make sure VisualARQ is loaded before opening Grasshopper. So close GH, run any VA command (i.e vaWall) and open GH again. Do the VisualARQ components appear in Grasshopper?
