MC5 / MC6 Dual Boot - Avid FX serial

Hi,

I recently bought a fresh copy of MC6, and updated a dongle accordingly, so I can jump back and forth between MC5.5.3 and 6.0.1 easily, if need be.

As MC6 still has some lingering issues with the MXO2 Mini, I had wanted to stay on 5.5.3 for the time being until the issues are resolved.

I`m looking to set up a dual boot on a new Mac Pro, that`s on its way in the mail, with Snow Leopard for MC5.5.3 and Lion for MC6.0.1...

My own concern is handling AVID FX and BORIS CC installers when moving between MC5.5 and MC6.

I have serial keys for the newest Avid FX and BORIS CC, but I`m wondering, are the newest versions of both of the software able to work correctly in 5.5.3?

And if not, could someone maybe provide some suggestions how to approach this then, I don`t know if the Avid FX / BORIS CCC serial keys are backward compatible with older versions of their own software.

Thanks

Alright. I sent a support form off to Boris, to see if there is a 32 bit version of Avid FX6.2 I can use with MC5.5.

Or if I can trade in my key for AvidFX6.2 for a AvidFX5.8 key, which is 32 bit, and get an installer from them.
