Hi, I'm trying to download Dropbox onto an old laptop with windows 7. The download does work except when I try to open files in excel, a number of files are missing. This is probably due to an error message I get once I have download Dropbox. The error message says something about an unsigned driver in the windows version and that I need a valid digital signature. It also says I need a digitally signed driver from the Publishers Support Website.
Is this something you can help me with please. Many thanks.
