WyUpdate.exe just tells me that I already have the current update
Running Setup.exe from a fresh download (as a Standard User, expecting to elevate when prompted) complains that "Another version of this product is already installed. Installation of this version cannot continue..."
Running Setup.exe as "Admin" prompts me to choose to install for "everyone" or "just me". I don't want to choose either option as I'm the only user who will use the tool and the admin account isn't my normal account.
In the end I had to do a full uninstall/reinstall cycle. I installed for "just me", but had to elevate to do so (surely that isn't right?). Regardless, it appears to run OK and it is build 310 rather than build 301 (I'd always avoid build numbers that have transposed digits, it's so easy for mistakes to occur).
