Re: "updatetool.exe has stopped working"

@iaf3ta  Try doing a clean uninstall of Origin and reinstalling the latest version.  Clear Origin's cache first, then uninstall "the hard way."  This shouldn't uninstall any of your games.

Instead of downloading the ThinSetup, use the full Origin installer.  This is the direct download link:

Be sure to run the installer as an admin, as in, right-click on the installer and select "Run as administrator."
