it forces IDM to download these files thereby forcing it to create certain keys in window's registry that the script is expecting in certain locations.

These files are downloaded to create Windows registry key which the script will intercept and use the info to add the registration key and freeze it so idm can't write those keys. If idm rewrite those keys, your license will become invalid.
