I have the DE1 board from University Program, and I need the DSP builder license; when I'am triying to obtain the license it is asking me for the serial number of my kit, I have and type the serial number but appers the next message: "The Serial Number you entered does not exist in our databases!".The error message that I obtain when I use Signal Compiler in simulink is "Error: Can't get license for C4D5_512A Error: Error opening input file for decryption " Help Me please.
I do not believe that the DE1 kit includes a license to allow usage of the DSP Builder blockset within the MatWorks tools.This is why you are getting the error message you are getting. Ask your prtofessor if they have a license file with the code to allow usagew of the DSP Builder Blockset. The license file will have a line in it wit the code C4D5_512A. That is why you are getting the error message you are getting.
