I am running Lightroom CC 2015 on Windows 10. With most recent updates, I have tried to update my version but I get an error message that the downloaded files cannot be opened, but there is nothing evident as a download. The update then "fails".
Please quote the exact complete unedited word-for-word error message.
First message (in red); "Update failed - learn more"
Clicking in learn more gets: "Unable to extract the downloaded files. Press Retry to download again (U44MV1I210)" or (U44MV11210= hard to read))
