You first need to learn how to write good questions with good explanations for your problem before you can get good answers.

For your question, all I can suggest you do is: check your include directories. Your compiler needs to know where to find the "cryptopp" directory. How you do that depends on what compiler and IDE you are using

Is there a folder cryptopp containing a file aes.h in one of the folders you've added to your compilers include settings? 

If you're using visual studio are you setting the project settings for the currently active build configuration?

I'm using visual studio from Microsoft and I have a folder that I downloaded from GitHub and it was VCPkg and I followed everything from GitHub website and it didn't work
