I am running Vegas 19 (Build 550) and a pop-up tells me there is a "major update." Yet, I click on the update now button, it downloads to somewhere on my Windows PC (Windows 10), but never updates. I searched through "documents," "downloads," and "Program Files - Vegas" to no avail. You guys have me stumped. No error messages, no update after I specifically do all of your instructions. Please advise.
