If you go to tools...options...searching, you can choose whether to be warned about downloading a file without a license.

Also, if you are going to try downloading programs from LW (I do), google the program first. The program may be freeware! Also, you may want to download a trial version from a more reputable source to see if you even like the program. It is always preferable to get the program from the people who make it. The decision is yours.

Good Luck
