[winafl]Client library targets an incompatible API version and should be re-compiled

If you get this error means your drrun.exe and winafl.dll is not compatible and you need to compile winafl again.

follow this process:

1. git clone winafl to your system from here:
   https://github.com/googleprojectzero/winafl
2. open visual studio command prompt(you need either vs2015 or vs2017 installed on your system for this)
3. go to winafl dir and run following commands for 32 bit build:
   mkdir build32
   cd build32
   cmake .. –DDynamoRIO_DIR=..\path\to\DynamoRIO\cmake
4. for 64 bit build run following commands:
   mkdir build64
   cd build64
   cmake –G”Visual Studio 10 Win64″ .. –DDynamoRIO_DIR=..\path\to\DynamoRIO\cmake
   you are done.
