Re-install of all components including the vsphere client yields the same results. My co-worker is on 32-bit Windows 7. I'm guessing that has something to do with it. The viewer windows do not come up no matter what method I try. I was wondering if it had something to do with the path to vmrc, which is C:\Program Files (x86)\VMware\Infrastructure\Virtual Infrastructure Client\4.1. I copied that to a different path, but it still did not work. Using process monitor, I watched for a spawn of vmrc, but it does not appear to be launching at all. Thanks.
