VMware Horizon Client Disconnects Immediately After Connecting: HccChannelPlugin::ChannelAddRef: No shared memory channel

Recently I’ve needed to connect to a virtual desktop using VMware Horizon Client. Immediately after connecting, I received the error message:

ERROR (1FD0-19D0) <6608> [vmware-remotemks] HccChannelPlugin::ChannelAddRef: No shared memory channel. Horizon client service may be down.
FATAL (1FD0-1E14) <vmware-usbd> [vmware-remotemks] GOT DEP ACCESS VIOLATION

After much research and try & error, I was able to determine that VMWare Horizon Client requires up to 4GB of RAM for physical machines and 5GB of RAM for virtualized Windows 7, 8.1, 10 systems (VirtualBox, VMWare Workstation).

  1. I was able to start the virtual machine with 2GB of RAM, and the combination of disabling 2D/3D acceleration *AND* disabling unnecessary Windows services (http://www.optimizingpc.com/windows7/optimizing_windows_7_services.html) allowed me to connect to the VDI via VMware Horizons client. I was able to use two virtual screesn at 2560×1440 with 128MB (virtual) video RAM assigned to the vm.

    ** using VirtualBox with VirtualBox Additions installed in the vm
