Understood. Have you reached out to him? If the problem has not been resolved it should be escalated to the support hotline (so a developer can take a look). I will email him as well.
.. this analyst is talking about my problem. I'm from Poland.
Cleaning everything what has "FreeFlow" in name in Windows helps me to install 188.8.131.52, but new version (184.108.40.206) doesnt install properly.
Problem has been not solved...
I just saw a report from an analyst indicating that they had the same problem. Using CCleaner on the client computer resolved the issue. It seems it was a silverlight issue of some sort. I would suggest trying that and escalating to support if that does not resolve the issue.
