I tried to download a new version of Zotero, and now I cannot even get into Zotero. It keeps telling me that I need to reboot. I have rebooted several times and it still does not work.
Download the installer from zotero.org and run it as an administrator (right-click the icon and select "Run as Administrator" from the context menu).
If that doesn't help, or if your configuration does not allow running it as an administrator, delete the entire folder where Zotero was installed and run the installer again normally.

We are working on a fix for this issue.
