thanks john, that was a valiant effort but it is nowhere to be found. V14 still supports it and tells you if it's not installed, so it must still be available from Magix. Time to contact support I guess.
If I recall correctly, MM for Vegas was broken in the latest releases of windows 10 anyway. Maybe try something else like Adobe Bridge CC ( it is actually free; no subscription required), or grass valley MYNC....
I use windows 7. None of the links on Magix or Sony's websites lead to a download of it. The version I have must be the latest and it works fine on Windows 7. I was just looking to see if there was an updated version of it. I like it better than bridge and haven't seen anything else on the market as useful.
Official reply from Magix:
"As Media Manager has not bee fully supported since VEGAS Pro 11, we do not have a separate install for it. You may be able to find the installer on original media for previous versions."
I still use it with ACID Pro 7, but find it is a little slow. Must be getting to be pretty old technology by now. Maybe we will see something new for Vegas 15, but doesn't seem likely to be an update of MM.
