Performing upgrade from 14.3 to 15.1 and trying to uninstall the 14.3 version of the XOG client. Opened the Programs and Features, selected the XOG client and clicked uninstall. Received Window's Installer prompt asking for the path to a folder containing the installation package 'XOG.msi' file. The 'XOG.msi' file does not exist on the server anywhere. Any ideas?
