The other way is the easiest way . After cracking and patching IDM, just go to the installation folder of IDM �C:Program Files (x86)Internet Download Manager� and rename the �IDMGrHlp.exe� to anything you want or just delete it. Done!
But wait! Every time you run IDM, there would be a new popup box saying �IDM cannot find 1 files that are necessary for browser and system integration. Please reinstall IDM�.
