Error Message: Need Mac Version 10.7.0 to install LR5 from disc

[nIkedoni1a]

I am trying to install LR5 as an upgrade (running LR3 now). My computer is running snow leopard 10.6.8 and the install disc for LR5 is telling me that it requires 10.7.0. When I run "software update" my computer tells me it's up to date. Is there a work around or do I need to upgrade my OS? Thanks

You have to upgrade your OS.

10.8.4 is the latest.
