Flash Builder 4.7 downgrade to 4.6 version

Hey,

We have bought a license key for upgrade from Flash Builder 4.0 SE to Flash Builder 4.7 SE, but we need access to Designer View which is not available in FB 4.7.

Our distributor tell us, that it is possible by doing downgrade to Flash Builder 4.6. To do it we should contact with Adobe Support.

So our questions are:

1. How can we downgrade Flash Builder from 4.7 SE to 4.6?

2. Could we change our license key to 4.6 license key?

3. How can we download Flash Builder 4.6 binary files?

Best regards,

Juri
