When WL mail began to load messages with the wrong header  or missing message even in my storage folders I followed the advice of a Microsoft tech, tried to repair installation and after that didn't work uninstalled it completely after exporting all messages to a new folder. When I reinstalled it  the dll files were missing and suggestions were they were in shared folder. Mine were not nor anywhere on pc. Tried to do deep uninstall and cleaned up remaining files in registry and in appdata/local/microsoft/windows/windows live. Now when I try to install, installer says all programs are installed but they are simply not there. Any advice? Not an idiot but this has me baffled. Have rebooted   after every operation. Thanks.
