Zotero 7 install does not work - because it does not uninstall

Hi, I think I have the same problem as other users. I installed Zotero 7 32 bit, got the prompt to install the 64 bit Version. Did it - I have not all admin rights but I have the admin name and password. I used that. Closed Word some point. Now I am stuck. I get the message that I have to reboot the computer again and again. But the reboot does not work.

Currently Zotereo is not running, but it is shown twice in the installed Apps

I have to folders. One in the folder "Programme"

Another one in the folder "Programme (x86)

The zotero menu is still visible in Word.

What should I do? Can I just delete the folders and reinstall? Which one

Thanks in advance for your advice in

    You can just delete both of those folders and reinstall the 64-bit version.

    @fishfishf: Before you do that, though, I'm curious: have you tried simply re-running the 64-bit installer? What exactly happens if you do?
  • fishfishf
    Oh no! I missed your second comment. I deleted the folders already, and now everything works well. My apologies!

    Thank you for your quick help and your great work. The new Zotero looks fantastic, and I look forward to using it.

    OK, no problem. Glad it's working now. We'll try to figure out what's happening in these situations.

    @dstillman - however, it still shows two installed Apps in windows

    When I try to uninstall the version not showing the logo this message pops up

    I assume that is not a problem. Could I do something to solve it or just leave it this way?

    I'm not actually sure how you ended up with two entries there. You can try 1) uninstalling the 64-bit version (with the proper icon), 2) reinstalling the 32-bit version, 3) uninstalling the 32-bit version, and then 4) reinstalling the 64-bit version.

    (It's also possible to fix this in the registry, but that's more complicated.)

    Did that, but did not work. I did it twice. First the way you suggested. And secondly I installed the 64bit version of the 32bit version. But still two entries and the same error message there.

    Your are right: The second entry is indeed a left-over of the 32bit version.

    Do you have any advice how to fix it in the registry?

    Can you say what exactly happened when you followed my steps? We'd like to make a more general fix here. People obviously can't be going into the registry to fix this.

    I did this

    1) uninstalling the 64-bit version (with the proper icon),

    restart

    2) reinstalling the 32-bit version,

    The next step was a bit tricky. First, the uninstallation did not work. I could ask to uninstall it via the "installed apps," but nothing happened. I tried this three times. once before the restart and twice after the restart.

    Managed to uninstall it by going to the Zotero folder (Zotero/uninstall) and starting the "helper.exe" with admin-rights

    After a restart, the entry was still in the installed apps menu of Windows 11.

    The installation of the 64-bit version added the second entry.

    ---
    Then I uninstalled the 64bit version again
    That entry was then gone.

    installed the 32bit version again

    result: one entry in the installed apps menu

    installed 64bit version without uninstalling the 32bit version - same result as before

    two entries in the installed apps menu

    Many thanks. That worked. However, I had to use a different location.

    Instead of this key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

    I had to use this one:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall

    just to let you know, in case somebody asks again

    Many thanks for your help
  • dstillman
    Ah, that might be a clue here. Thanks!
