Version 7.6.1 jnbSA at 32bit available für Citrix environment?

Experts,

currently we are about to upgrade our Netbackup environment from 7.5.0.6 to 7.6.1. Our administration console is the Java GUI jnbSA installed on a Citrix Metaframe (32bit only). Now we found out that 7.6.1 has a 64bit version of the Java GUI only. Is this true or can we found a 32bit version somwhere else?

Thanks in advance for your hints!
