I already have vSphere Client 4.1 installed on my 32bit Windows XP machine. When I used it to connect to an ESXi5.1 host, it wanted me to upgrade to vSphere Client 5.1.0. Just before the installation can complete the error below pops up.
Does anyone know how to fix this?
Take a look at http://www.itninja.com/question/vmware-vsphere-client-4-1-msi - relates to 4.1 but should apply. Alternatively try and ensure your vi client for 4.1 is completely uninstalled and then try the 5.1 client installation.
JCMorrissey, I saw that link before but it talks about packaging an installer. I uninstalled VI Client 2.5 and vSphere Client 4.1 but still get the error message. I did other things but I think what fixed my problem is the installer I downloaded from another PC using IE8. I'm using Firefox 12, large downloads tend to be corrupt or interrupted before they finish. This problem is solved. If users get the error above, I recommend you re-download the installer from another PC.
