QRC: *Error* load: can't access file "[...]/ext_18.12.000/tools/extraction/bin/32bit/etc/context/6.1.0/qrc.ini"

Hi! When I launch the "PVS->Run LVS..." command in a layour editor, I get the following messages in the CIW:

QRC: *Error* load: can't access file "[...]/ext_18.12.000/tools/extraction/bin/32bit/etc/context/6.1.0/qrc.ini"
*WARNING* (DEBASE-102079): A SKILL error occurred in function CCSSetupQRC

In my QRC installation the "[...]/32bit" directory does not exist, but the "[...]/64bit" does. Moreover, I have the environment CDS_AUTO_64BIT variable set to ALL, but it seems CCSSetupQRC is looking for the wrong executable. How can I solve this issue? I am using ICADV12.3-64b.500.17 with PVS 16.12

Thanks and regards, Jorge.
