PT12 download question

I bought the PT12 upgrade for my HD system on Xmas Eve and the local vendor was able to get avid to put the PT12 bundle licence into my ilok account, but avid hasn't sent me an activation link so i can't download the HD software until avid gets back from holidays. I also own an Mbox Pro 3 with a licence for PT12, and I'm wondering if the same software will work with my HDX system?

the file is: Pro_Tools_12.4_Mac_88973.dmg.

or is the 12 HD software different? I should know this (and i expect the answer is no), but I don't...

thanks,
