Chromodo update error

When trying to update to Chromodo 42 I kept getting an error message (see attached screenshot). I was in the standard administrator account on Windows 7 Professional SP1. I was able to install it by using the higher level, hidden administrator account, something I have never had to use until now. It does not seem wise to force people into that account to install something, given the account has unrestricted access to the entire computer.
