Problems upgrading to 7 and then 64-bit

I upgraded Zotero to version 7. It then told me I should upgrade to the 64-bit version, so I did that, too.

I believe I finished the upgrade, and it told me to reboot, which I did.

Now, any attempt to run Zotero, rerun the 64-bit installer, or uninstall Zotero causes the same message:

Your computer must be restarted to complete a previous
upgrade of Zotero. Do you want to reboot now?

(Yes) (No)

I've replied Yes and rebooted by computer several times, but the message appears every time I try to run Zotero.

I'm running an up-to-date Windows 10 Home on a Lenovo laptop.

    That's not good, but you can just delete C:\Program Files (x86)\Zotero and C:\Program Files\Zotero and reinstall.
  • @lagbolt: Actually, before you do that, can you take a look in those folders and let us know what files still exist?

    I'll also wait in case you need more details.

    Thanks for your prompt response,

    -- Graeme
  • OK, thanks. Could you both email install.log from both folders to support@zotero.org with a link to this thread? After that, you can go ahead and delete those folders and reinstall.
  • logs sent, files deleted, reinstallation worked

    Thanks

    Edgar
  • Same!

    Thanks for your help.

    -- Graeme
  • I also hit this issue, but it was resolved using the steps outlined above. Many thanks.
  • Thanks to everyone for reporting this and sending in additional info.

    In 7.0.1, available now, the installer will provide an option to delete the previous installation folder if it's not automatically removed, avoiding the reboot loop.
