Would appreciate if you could look into the problem.
Build from today (30.07.2014 - Build No. 857) is still not usable and shows the same behavior.
Everything works fine here with Build No. 857 (as soon as I close the warning message because CrashSender1402.exe is not there). Unfortunately I can't help more as long as I can't reproduce your problem locally.
I'll commit a fix for CrashSender1402.exe + alert message at the end of installation this weekend.
