Impossible to reinstall Zotero

Amarq
Hi there,
I uninstalled Zotero and now I can't reinstall it. When I launch the launcher, I get a message asking me to restart the computer to uninstall Zotero... I have tried to download and delete the launcher several times without success... I can download and use Zotero 6, but I am still stuck on Zotero 7.

I guess I have a kind of "cookie" of my computer since Zotero seems to have kept in memory my first desinstallation, but I was unable to localise it...

Can you help me? Thank you very much!

    This is related to user privileges on Windows, and we've already fixed some cases where this would occur, but clearly not all.

    Could you please help us by answering a few questions below?

    1. Does your account have administrator privileges? When you start the installer, does it show a dialog asking you to allow the installer to make changes to your system?
    2. Where is your Zotero 6 currently installed?
    3. When installing Zotero 7, if you select "Custom" instead of "Standard" in the installer step visible in the screenshot, it will show a path where Zotero is to be installed. What is this path?

    Thank you a lot for your help.

    1. Yes, I have to allow the installer to make changes to my system.
    2. C:\Program Files (x86)\Zotero
    3. C:\Program Files\Zotero\

    I hope this is the aswers you asked for.

    Thank you for providing the extra information. It seems there are files in C:\Program Files\Zotero\ that should have been removed during the uninstallation (or a reboot afterwards) but weren't. To solve this problem, you can manually remove the C:\Program Files\Zotero\ directory and run the Zotero 7 installer again.

    If you wouldn't mind answering a few more questions to help us track this issue down, I’d greatly appreciate it:

    1. Did you uninstall Zotero prior to running the Zotero 7 installer? If yes, do you remember how you uninstalled Zotero? Was it using the "Add or Remove Programs" feature of Windows?
    2. Did you ever have an earlier version of Zotero 7 installed?

    @Amarq: A screenshot of the contents of C:\Program Files\Zotero before you remove it might also be helpful.

    Hello,

    1.Yes, I initially uninstalled Zotero prior to running the Zotero 7 installer, using the "Add or Remove Programs" feature of Windows.

    2. It was my first version of Zotero on this computer.

    I finally removed C:\Program Files\Zotero\ manually as proposed, and it worked, thank you! But I'm sorry, I did this before the screenshot...
