As i mentioned in the previous post we have to change the SDK’s and to do this download it from Adobe labs and paste it in the Adobe->Flex Builder->sdks-> folder the default name of the folder is enough to include, no need to change the folder names.
Now open your flex builder and open any project ,right click on the project select properties then you would get a screen like the below.
Select flex compiler and at the right hand you would fine “configure flex sdks“[marked in red] select it to include sdks.
Then the screen would be like the below.
Here click the add button[red marked] to add the sdks ..
Click browse button [red mark] to include those sdks which were pasted in flex builder -> sdks folder and they are include and after that check it and include those and they are included and error is expired.
Final screen to check the sdks..
click apply[bottom red marke] button after checking up [red markd] including those new sdka.
Thats all the the problem is solved “The Error is finally expired” . And no need to install again Flex Builder.
