Question: Can I create a custom version of the mIRC distribution files, or distribute mIRC as part of my script?
Answer: Sorry, this is not permitted by the distribution license. If you are creating a script, you must distribute your script as a separate file, and ask users to visit the mIRC website to download mIRC if they don't already have it installed.
