Documents\MAGIX Downloads\Installationsmanager is where i have found previous builds, like Vegas Pro 17 build 353. However, after installing the latest build 421, I cannot find the big file for installation that I want to use on 3 other computers.
I did not find it on the computer that I upgraded a week or two ago to build 421. Only older upgrades. However, I downloaded onto a different computer once more, and this time I found it where you would expect, so I have at least saved 2 more downloads. (I do not know why that one install did not keep the file.) Thanks for helpful comments.
