I'm having the same issue as well with my DCS, but I never got the prompt. I've reset it, unpacked it multiple times and nothing. Did they ever give you a solution to the problem? If so, could you post it here because it would be a big help.
I updated Viewer 2 to 2.7.1, but several of the drivers wouldn't extract without an error message. The viewer still runs but i'm concerned with whether or not they will have some sort of impact on SL. Here's a list: zlib1.dll winmm.dll vivoxsdk.dll vivoxoal.dll ortp.dll libsndfile-1.dll SLvoice.exe
