Cadence 6.1.7 on CentOS 7

Hello, 

I have installed Cadence 617 that runs from a RHEL server 5.6, when I try to launch virtuoso I receive the following message. 

Make sure that cdsGetOABinPath is part of the Cadence installation

Error: No proper OA2.2 installation found. 

Any help would be great. 

Thanks
