No free registration exists for Internet Download Manager. However, a free 30-day trial version is available that does not require registration. Once this time expires, the user has to register the application to be able to continue using it.
IDM software has to be purchased before IDM can be registered. Necessary registration information is sent after the purchase, including a serial key or number to be entered on the registration dialog.
Running patches or using a cracked version of the IDM application isn't recommended because patches and cracks may infect the user’s computer with viruses. They may also create a security breach that can be used to access personal information such as banking accounts and credit cards.
