Do 32bit and 64bit CS4 come on the same disc?

[joey1211]

Currently running CS4 on a 32bit system and am thinking of upgrading to a 64bit system?

Am I right in thinking that the 64bit version shares the disc with the 32bit and I will only need to transfer the licence?

Thanks

Only Photoshop is 64 bit enabled my Design Premium and it was on the same disc. It's an option when choosing the components during install.
