Google has announced that Google Drive will stop working on 32-bit windows 10 computers and all running Windows 8 or 8.1.
This will happen in August. To check whether you have 32-bit windows, open ‘settings’ and go to ‘system’. Under Device specifications in the middle is System Type. See whether it says 32-bit or 64-bit. If it says 32-bit does it also say x-64-based processor? If so, you can upgrade to 64-bit windows by doing a clean install. Just make sure everything you want to keep is backed up and you have all the program installation keys (but you don’t need the Windows one).
If you don’t upgrade, you can still use Google drive through your browser.
