You should only use this for testing purposes... Download the latest 4.2 iso image from Citrix website. Use VMWare Workstation v5.5 (should work on gsx and esx) Create a new virtual machine and select "other and other" for the OS. Use the 4.2 iso image and mount it on the virtual CD rom in your new machine. Create another NIC for the virtual machine - use host only for networking for now. Once the machine is created, close vmware. Open the .vmx file for your new machine with notepad and add the following lines ethernet0.virtualDev = e1000 (should come after the line Ethernet0.connectionType = "hostonly") ethernet1.virtualDev = e1000 (should come after the line Ethernet1.connectionType = "hostonly") Start the virtual machine Wait about 20 mins for it to install from the iso image Restart the virtual machine You may have to play around with your vmnet nic so you can start communicating with it, I changed mine from "host only" to vmnet8 in the virtual machine and then give the vmnet8 adapter on my laptop an ip address of 10.20.30.41 and it worked a treat.
