Flex Builder 3 comes with SDK for 2.0.1 and 3.2 by default, so I want to add Flex SDK 4.1
I downloaded it, made a directory in the Flex Builder 3 sdks folder, and unzipped the contents there.
After adding it and selecting/checking it on Flex Builder, I tried to use it by running a project I was using with 3.2 and I get the error below:
unable to open 'C:\Program Files\Adobe\Flex Builder 3\sdks\4.1.0\frameworks\libs\player\9.0\playerglobal.swc'
What do I need to do or didn't do?
You can not use SDK 4.1 in flex builder 3. You need to purchase Flash Builder 4 or use free SDK 4.1 in eclipse.
