Question or Issue
Dropbox kept asking me to update, but when I download the update is say "On your marks..." then the window disappears and nothing happens. So I deleted dropbox rebooted and tried again. Same result. So I downloaded the offline installer for the last version I had, and it won't install.  Gives the error log below. My wife and I each have a windows account on this computer and each have our own (basic) dropbox account. I've been using dropbox for years and never had any problem like this.
