When I open RS Config Manager I receive the following error, "Attempted to read or write protected memory. This is often an indication that other memory is corrupted." The articles I found on this on MSFT relate the problem to having Excel 2007 installed. I do not have office installed on my server. My server is a VM running on VMware ESX VI3 . The guest has been allocated 4 GB of memory. Any help would be appreciated.
