ESXI 5.5 supported or not?

Hi all, 

does Netbackup 7.5.0.6 supports ESXi 5.5 or not?

• in doc Support for "NetBackup 7.x in virtual environments" I found out that it is not supported, but 
• in doc "NetBackup 7.5 Feature Briefing Application Protection for VMware Virtual Machines" specifies that ASC supports 5.x

what does that mean? I'm a little confused here. 

help pelase. 

Regards,
