CS3 (on Windows 7) upgrade to CS4

Hello -

I currently have CS3 Master Collection running on Windows 7 64bit Ultimate RC. I know that CS3 is not certified to run on 64bit systems and yes I know that my version of Win 7 is a beta build.

So my question is:

- Once I get the *real* Win 7 OS later this month, would it be ok to install CS3 on there and then the upgrade to CS4?

...or

- Should I install a Win XP 32bit OS, install CS3, upgrade to CS4, then upgrade to Win 7?

I realize any which way I go, I'll have to de-activate, wipe clean the HDD, and then reinstall with whichever methods you experts recommend. Or maybe some other way you all can think of that I may not be seeing here.

Your best and maybe only approach is to reformat your disk and do a clean install of Win7. I think you can not upgrade from a beta to the final version.

Simply reformat your system partition while installing?Win7, then install CS4 products.

No need for XP or CS3.

Less upgrading - less problems.

I agree with the above.?When Win7 comes out, you'll have to do a clean install.?So you may as well just load up CS4 and leave CS3 out of it.

It's what I did.

Here are my PPBM scores for all three OS's under identical hardware conditions, as you can see below.?Win 7 is a definite win for Premiere Pro CS4!?These numbers shown are averages of many (%26gt;10) repeated runs.?For these benchmarks of course lower means faster--better.

I understand your point here BUT.....

....your method that you are describing sounds to me like I have to purchase a FULL CS4 version rather than an upgrade version....correct? Or does the upgrade version just need the serial / registration / activation number, code or whatever from my current CS3 and not necessarily be installed?

So here's what I was thinking that I could do:

- Buy Win7

- Install on new HDD

- Install CS3

- Buy CS4 (UPGRADE Version)

- Install it

- Start using it!!

Your thoughts?

No need to install CS3, just have the serial number ready or the original disk when asked for it.
