Beamer License Invalid

"The license contains invalid data"

Strange I tested the license before uploading.

Invalid for me too.

Hello, Try this Patch:

Put Beamer 3.3.3 in Applications folder.
Open the Patcher and press Patch and open Beamer App (It may ask you to install Xcode Tools you must do this).
once Patching is done try open Beamer.
If still asks for license close Beamer and open the Patcher again and Save a license file to your downloads folder.
Open Beamer and open the license file you just saved.

This is what worked for me.

Well, Can't install xcode tools as it is currently not available in the server

Tried your patch but when it try to install xcode tools it says software is no more available on the server

Download Xcode and then install Xcode tools.
