    New to ESXi 5.1 - errors in VSphere client on Windows 7. Please help!

    Tanny1 Lurker

      Good Afternoon everyone,


      In an attempt to introduce myself to VMware virtualisation I have recently installed ESXi 5.1 on an HP N40L microserver with 8GB RAM however have run into problems when creating my first VM. I am uisng the vSphere client downloaded onto my Windows 7 64 bit laptop from the link found in the page when pointing my browser to the hosts IP address. I have tried numerous fixes outlined in the KB’s and other sites to no avail. I would greatly appreciate all and any assistance.


      I can create a new VM but get the error “An internal error occurred in the vSphere Client. Details: Exception has been thrown by the target of an invocation.” when I click on the new VM in the inventory in the left column. I can power on the newly created VM but if I right click the VM to open console I get the following error: “An internal error occurred in the vSphere Client. Details: The requested name is valid, but no data of the requested type was found”. If I press close I then immediately get the dialogue “An internal error occurred in the vSphere Client. Details: Object reference not set to an instance of an object”.


      I have uninstalled and reinstalled .net framework 4, uninstalled and reinstalled the vSphere client several times, rebooted machine in between. I have also set the Data Execution Prevention to always off as suggested by some users (bcdedit.exe from CLI) but nothing is working for me. My machine is healthy, no malware, Windows is all up to date and using Microsoft Security Essentials for antivirus. I don’t know what else to try and currently this is the only client machine I have access to.


      Please can someone advise what my next steps are? I thank you in advance. I have attached the logs generated by vSphere if you would like to take a look.
