i have installed adobe air and everything id need but everytime i try to install it tells me that my installer is damaged i am using windows 8 and i am out of ideas to fix this

This happened to me too also. I am not sure of what to do. Try reinstalling AIR, refreshing the page, or reinstall flash. Also, to have more system settings in your forum posts, click the globe button next to the smiley face and scratch blocks button.

To be precise, what fastmapler is referring to is this icon:

Often this happens when there was a bit of an error in your download somewhere and it was undetected by the downloading daemon. Try downloading Scratch again.

To fix issues with Adobe Air, have a look at their help page at http://helpx.adobe.com/air/kb/troubleshoot-air-installation-windows.html
