Be prepared :-) This question may be very dumb, as I have zero experience with Flash (although I have programming and developer skills in other areas as .NET, Java, Web Development, SQL etc)
I've tried to Google it but still I am confused.
My main question: Is an .fla file a source or it is a compiled output? If it is a source then how to author it?
I see it is a .zip archive with .fla extansion. My guess is it must be a source, then why I can not open it with FlashBuilder? I've installer FlashBuilder 4.5.1 (that is what I have) and it does not even offer this extension in the File/Import Flash Builder Project dialog window.
I've also tried File/Open File. I got modal error message window: just get this message "Windows cannot find 'Flash'. Make sure you typed the name correctly, and try again." In Preferences/File Associations for FLA Adobe Flash Editor (default) is selected.
It is a Windows 7 machine, with a fresh Flash Builder 4.5.1 install.
Thanks in advance
