hi .. how are you guys, i made a project in adobe flash pro CS5.5 and i should show it today in my college but... we dont have there except macromedia flash 8 , can you guys help me please to avoid this problem
You posted at a bad time to expect immediate responses..
It depends on what you need to show. If you only need to show the working output file then you can publish it as an exe file and that should be able to play on whatever machine is at your school. You could also probably publish an swf and open it directly in any browser that has a more recent Flash Player installed.
If you need to show and demo the design file (fla) then that will not be possible using Flash 8, especially if you designed it with AS3 because Flash 8 was created before AS3 existed. If it was designed in AS2, then you could save it back to Flash 8 if you have every version of Flash back to at least CS3 at home.
