Upgrading Zotero does not work

Zotero produced an error when trying to update the dadabase.

Error code: 1987310541
  • Now I can use Zotero, but I don't know if any data is lost...
  • Restart your computer and try again. If that fails, reinstall 2.0 and try again.

    If that fails, do you have anti-virus software or other background utility software on your computer? Are you trying to install onto a network drive of some sort?
  • No data was lost—it was just updating the translators or styles, and the unzipping operation failed. That shouldn't happen normally, so it's likely some problem on your computer or a corrupted download. To make sure you have the latest translators and styles, you can just go to Reset Translators and Styles from the Advanced pane of the Zotero preferences.
