Internet Download Manager (IDM) shows the download panel when web-player in browser requests multimedia, for instance, when you visit YouTube site and play any video, then download panel with ‘Download this video’ button appears, which further on clicking lets you download that video in MP4, 3GP, FLV, MP4, WebM or other file types with different quality.

Fix ‘IDM cannot find 4 file(s) that are necessary for browser and system integration. Please reinstall IDM’
