Usually you install the exe.file, and after the installation is complete, you go to the installation folder where you copy the crack file.The crack file looks could be named with exe also , so wht you need to do is copy it, and if a window pops up and asks you if you want , to overwrite cause the file already exists, you click yes.
All exe.files means executable, that means any program has one, and to install any program you need to run the executable, click next, next and finish. And remember where u installed a program(usually , in C/PROGRAM FILES/NAME OF THE PROGRAM. )
USUALLY U CAN RECOGNISE THE EXECUTABLE BY THE ICON, CAUSE IT HAS THE PROGRAM SYMBOL ON IT. .tHE CRACK LOOKS IDENTICAL WITH THE EXE .FILE,SO DONT CONFUSE WICH IS WICH, OR THE PROGRAM MIGHT NOT RUN AT ALL.
