spectre 32 bit or 64 bit?

Hi,

Ok, I am just an administrator. One of my users is adking me, why spectre gets invoked from 32bit directory instead of 64bit. 

 Here is the log snippet,

OS also is 64 bit linux,  Cadence (R) Virtuoso (R) Spectre (R) Circuit Simulator version 7.1.0.060.isr4 -- 25 Mar 2009

If you need any other i/p let me know. Thank you.
