What kind of licensing is required for using Adobe Flex Builder IDE for building Flex Applications?

[Guest]

I am looking for an IDE to build Flex Applications. Can you suggest what IDE to be used for this and what are the licensing I should procure for the same? What kind of support will be available with that license?

Don't buy Flash Builder 4.7. It doesn't work fine!

Thanks Empardopo.  Do you have any suggestions? What kind of problems do you see with this tool. Also does Flash Builder 4.7 supports Flex SDK 3.5?
