Installation hangs on Mac OS X Lion

[numinuma]

I downloaded the flash builder trial version from the web. Started the installation, entered the serial number which I received in the email.

But it hangs as soon as I start. See the attached screenshot. I am not sure what is going on. I restarted the computer, closed all apps, removed previous version of FB but to no avail.

My environment is Mac OS X 10.7.1 (Lion)

What am I doing wrong?

It sounds like you have (or had... this was a month ago) the same problem as me. My solution is posted here: http://forums.adobe.com/message/4052808
