How to Fix Illegal Program Detected Issue in MapleStory M

Recommended Videos

It’s one of your most dreaded fears, and now it’s here before your very eyes: “illegal program has been detected”. Not only is it lacking in grammatical elegance – periods are important, guys – but it forbids you from accessing MapleStory M.

So what gives? Why have you been able to access the game perfectly unimpeded, only to have this warning pop up now, of all times? The first thing to realize is that the program detection system isn’t perfect; it will miss things upon launch sometimes, and catch it later on.

The most obvious fix, clearly, is to uninstall any cheat programs that you may have on your device. Anything that is made with the intention of altering or hacking the game should be uninstalled immediately. Otherwise, you run the risk of your account being banned permanently. Note that you do not have to be running these programs during gameplay in order for them to be detected; if the scans detect it, uninstalling is your only option.

The illegal program message is also known to trigger in phones that are rooted or jailbroken. If your phone is second hand and you are unaware of its background, this could potentially be the case, as well.

As a final fix, try reinstalling MapleStory M and relaunching it without any other programs running, even ones that are completely unrelated to hacking. You might have an innocuous app that is somehow triggering the warning.

Failing all of this, your best bet is to get in contact with Nexon directly and report your issue. As MapleStory M is newly launched on mobile, it is bound to have some hiccups here and there, and the best way to prevent this from happening is to inform the developers quickly and politely.

Hopefully this will help you get back into the fun. For more MapleStory tips and tricks, search Twinfinite.
