I'd like to add that even in VMware View 5.1.1 this problem is still going on if you use Sophos for Anti-virus.
Removing Sophos solved my issue!
We are having this issue every now and then and we are running Trendmicro. Win 7 x64. A Reboot fixes it. Very annoying!
The solution was exactly to give you an exception for the antivirus to allow the dll of vmware, the antivirus in my case sophos.
Hi marlont_1. What are the exact vmware dll exemptions you added to your anti-virus?
