So we did a server upgrader here and installed a new server to take over for Exchange.(it has been having problems).
New server install went great. Mail is now sending and reciving properly through the new Exchange 2010 setup.
I am now ready to uninstall the old Exchange as to remove it from AD and the New Exchange Server's EMC.
However, when I go into Programs and features and click uninstall right away it fails with the error "EXSetupUI.exe has stopped working" and I can go no further.
