For develop in Flash do I have to buy licence?

I am a student a I have to develop a simple application in flash and FMS.

I don't have开发者_Go百科 money for buy flash.

How can I do ?

The option I'm currently using is FlashDevelop + Flex SDK (both free, you can get the Flex SDK at http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+3 -> stable builds -> Adobe Flex SDK ). What you get is something similar to Flex Builder, the drawback is that there's no graphics editor built-in.

The Flex SDK is free.

Adobe gives you a trial period of flash for 30 days. If you have not installed flash on you machine you can download it here, http://www.adobe.com/products/flash/ click on the try button.
