I am running windows 7 home premium and from the time when I downloaded the movie maker essential beta I obtain this error when open movie make. Error Message:"ux core.dll missing" as well as when I restart my computer I obtain; "wlidcli.dll missing" It will not permit me on the way to uninstall the download as well as I cannot even open movie maker. What can I do? Please suggest me any solution to get rid of this trouble. Your suggestion would be appreciated. Thank you in advance.
