    Lightroom 2015 (Ver. 6.7 upgrading)

    Rossi Cesare

      I use the 6.7 version of Lightroom 2015 without problems but I can not install the latest upgrade (download stops to the 50%, in creative cloud), error code U43M1D207, "The signature of the downloaded file is invalid." I tried to create a new user, and download from there and I have tried deleting or renaming files in the user / AppData / Local / Adobe / AAMUpdater and OOBE (opm.db) and Temp (AdobeDownload and Log). I have a hp envy23 desktop, Windows 10 Home X64, Version 1607, Build 14965.1001
