Answered: SUITE 2.2.1 failure to launch

I upgraded from 2.2.0 to 2.2.1 and since then SUITE hasn't worked. Nothing appears to happen when I launch the suite, nothing in Task Manager, but in Process Explorer I can see the Suite sitting there doing nothing. If I use Process Explorer to kill the process nothing happens, trying to kill it again gives me an "Access Denied" error, and then I have to restart to really kill it.

I thought I had fixed it by reapplying the 2.2.0 patch then re-upgrading to 2.2.1; the suite would launch, Ndo and Ddo would launch, but every time 3do would either hang at 80% or hang at 80% and then freeze the suite...so that didn't work.

I've tried a fresh install of Photoshop, a fresh install of the Suite, running the Suite/3do/Ndo/Ddo as an admin, not running the Suite/etc. as an admin, running everything but 3do as an admin, running Photoshop as an admin and not as an admin, reapplying the patches, installing into another folder such as "SUITE 2.2", installing to another drive, updating .Net and Java, installing a different C++ redist.

I really want SUITE to work, it was very cool when it did work, but I don't know what else to try and restarting over and over to kill the suite process is making me want to ask for a refund.

my specs are:
Win 10 pro
Photoshop CC 2015.5
GTX 980
i7 5820k
