I've ran into an issue with the latest versions of the client and agent that I cannot resolve. I first discovered this when installing the 6.1 agent in a windows 8.1 Enterprise VM, upon boot the ctrl+alt+delete screen would flash, then black. Pressing ctrl+alt+del would trigger the lock screen to flash, and then back to black. The only work around I found was to first install 5.3.3, then upgrade to 6.1, however this does not work in server 2012r2 since <6 is not compatible.
The continuance of this is that the same release generation of view client 3.3, causes the same behavior on a physical machine, and the only resolution was to boot into safemode and disable the view-client startup application.
If i connect to the guest with the client, after solving the issue on the physical PC, I get the same behavior on the lock screen as I do in vsphere client console.
Has anyone delt with this and been successful in resolving since I'd rather use 2012r2 datacenter due to licencing. I have even assigned 512mb video memory to the VM and vmware tools is up to date.
