I'm not sure how any of that relates to "installation" files. But if you want to avoid user editing you'll probably want to obfuscate the data (simple XOR with some pattern?) and if it has to be secure you'd want to use some sort of encryption. To tamper-proof it you'd use some sort of Public Key signature.
