I am just started to learn Flex myself. I just created a label and entered a text. After clicking RUN button, it gives the erroe as in the screenshot attached here. After clicking yes, it takes me to the command prompt. But it is not displaying the output. I have installed the latest Flash player from Adobe website. Kindly help!
Sometimes this can happen if you have Flex and Flash installed, and the player versions can mess things up. Just follow the link and install the requested version of Flash Player.
