Tools For MR 1.7.4 problem

So i have a MR816x running on version 1.7.2, win7, 64bit, with no problems, but when i try to update 1.7.4 I sometimes get a memAPI.dll register/unregister fail, and sometimes not. After a seemingly good install, the device will no longer be recognized by the computer. doesn’t even say its plugged in.

… i debate the importance of having this update to almost none for me, because i dont have C7, and i DO have the old 1.7.2 zip to go back to. (thankfully, since Strindberg no longer has it up)

ive tried this a few times, and i think ive tried using a TI firewire card with no results.
