Here it is :
Install it. When you install it you will have 2 folders : The Enigma Protector and Keks. Copy the files from Keks folder and paste them in The Enigma Protector Folder. If you get asked to replace, click yes. Now run the protector from the folder:
In right you will see "Input" text - You will see down from it "Select file to protect". Click browse and find the file you want to protect, then click "Protect" button at the bottom. Wait until you see the "Run" button ready and close the program. Go to the file's folder and you will have new file with same name , but protected also in it (ex. hack.exe , hack_protected.exe) The hack_protected.exe file is the protected one. Thats it.
I hope I helped
