FYI, I bought Blue iris V4 ran it updated it till the support ran out. Decided I wanted to move it to a different computer and that's when I figured out there may be some questionable practices with it? Like I said I had version 4 that had support for its limited time line. While I had support it updated from version 4 to version 5.4.6.3 (BUT) here is ware things go astray! By moving it to another computer you get SCREWED! because your valid key wont work for that new version! and I had to reinstall version 4 and that version will NOT let you update to the same version it DOWN GRADES you! to version 4 UNLESS you buy another key that will let you up grade it for one year for an additional $30 US.
Only running it on ONE machine replaced machine it was originally installed on!
