Doh no scratch that, it may not be there either I think Avid trimmed stuff there as well.
If you don't have it file a licensing (yes I know it's download not licensing) support case here:
https://www.avid.com/learn-and-suppo...-music-support
Post the case # here might help others from Avid follow up. Licensing related support cases are free.
And whatever you do in future... keep a copy of your installers somewhere, multiple copies, backed up. You will never know when you'll need them and stuff is not working.
