Head and brick wall comes to mind....
I don't see any security issue, if anything you should allow people to see what's being installed whenever they are silently installed or not.
It just seems strange and you are being vague with what you are asking and you are not listening to the same repeated answers which Scott stated.
Post some of this batch file leaving out any sensitive information you are worried about, but remember it's plain text, so you should not be storing passwords or anything sensitive in batch files anyway and even if you encrypted the batch file, the user will still need to unecrypt to run the file, so thats a flawed option.
If there is nothing malicious in the batch file, then you should have no issue posting it?
