Will a BC4 license key work with BC3?

Hello,

If you buy BC4 and find you need BC3, you can email us at [email protected] and ask for a BC3 key. The program won't accept a BC4 key into BC3 or vice versa.

Alternatively, if you purchase BC3, you can then immediately run through the Upgrade wizard to upgrade it to BC4 using the automated tool. Either path is fine, and if you have any trouble or questions, just contact us.

I noticed the BC3 and BC4 pricing are the same, so I might as well buy BC4. Then again, I have a Windows 2000 machine I want to install it on, and BC4 doesn't support Windows 2000 - only BC3 does. So if I buy a BC4 license key, can I use it for BC3?
