QRC Virtuoso invoke setup

Virtuoso Version: 6.1.8

Quantus Version: 22.1.0-p089

Assura: 4.1

cshrc script:

set path = ($ASSURA_HOME/tools $path)

set path = ($QRC_HOME/tools $path)

.cdsinit script:

qrc_home=getShellEnvVar("QRC_HOME")

loadContext(strcat(qrc_home "/tools/extraction/bin/64bit/etc/context/6.1.0/64bit/aux_qrcui.cxt"))

load(strcat(qrc_home "/tools/extraction/bin/64bit/etc/context/6.1.0/64bit/qrc.ini"))

When I start the virtuoso the message says that "The Quantus UI context file was successfully loaded."

I think I followed all of the manual to invoke QRC in the virtuoso, but I can't see QRC menu when I open "Layout Suite L"

Can you give me some advice?
