Zotero 7 portable failed to update! How to update it manually ?

Hi
I had tried multiple times to update it from 7.0.5 (64-bit) to 7.0.8 but got this message:
The Update could not be installed (patch apply failed)

How to fix this? or alternatively how to manually update a portable zotero ?
  • Sorry, we can only help with the official version of Zotero from this site.
  • It is an official version of zotero !
    I did download it from (https://www.zotero.org/download/) then (64-bit ZIP) link.
    I download and launch it successfully, my issue is with updating it.
  • Oh, if it's just the ZIP, you can always just delete the folder and replace it with the new unzipped folder.
  • OK. but I don't want to lose my library !
    If you could provide me with a link that explain data, addons and binary locations inside zotero folder, that might resolve this issue.
  • That folder has nothing to do with your data — it's literally just the same application files that you downloaded and unzipped.

    Data is stored in the Zotero data directory.
  • Thank you
