How will I use Quicktime Pro ?!

Keep it?

Are you upgrading to Snow Leopard? Then it will stay right there.

Your information is contained in the app, you know.

 

Isn't the registration name and code in the preference pane?

 

AFAIK when you upgrade Snow Leopard detects QT 7 Pro and will automatically install it. You can manually select it though.

As for your problem, the registration information is available in the QT pref pane under registration is it not?

 

Or log-in to the Apple Store online and get your code again.

Retrieving your QuickTime Pro Registration Code

When you purchase QuickTime Pro on the Apple Online Store, you receive your registration code instantly. Your registration code will be displayed on the Thank you for your order page immediately after check out.

You’ll also receive your registration code in you purchase order confirmation email.

You can also view your QuickTime Pro Registration code by visiting the Downloadable Software Purchases section of Your Accoun​

So, can I have both on a snow-leopard machine? Is that a fact?

Quicktime 7 Pro and Quicktime X?

I need Pro for the work I do but I like that Quicktime X allows screen-capturing! I´m just a little worried that you can have only one Quicktime version installed at a time.

 

Yes it's a fact, both can co-exist.
