Hi Dylan,
Thanks for responding.
Looking in the temp directory there is a yum errors log:
Error: Protected multilib versions: libstdc++-4.4.7-3.el6.i686 != libstdc++-4.4.6-3.el6.x86_64
Error: Protected multilib versions: glib2-2.22.5-7.el6.i686 != glib2-2.22.5-6.el6.x86_64
But there isn't an error log in /opt/
I'm not used to centos in any way, but it seems like I may have to remove duplicate packages?
