Check requirements
Your operating system should meet the requirements below for the DeepL desktop app to work.
DeepL for Windows
The minimum requirement for the operating system is Windows 10 (64 bit), including all editions.
The minimum hardware requirements are the following:
- 2.0 GHz processor (single core)
- 1 GiB RAM
- 500 MiB hard disk space
- A monitor with 720p resolution (1280 x 720 pixels)
Note that if you or your company use a proxy server, it might be necessary to configure the proxy in the app settings, depending on whether the app recognizes the system proxy configuration automatically.
DeepL for Mac
The minimum requirement for the operating system is macOS 14.
Ensure network requests aren't blocked
If your desktop app is not working as expected, a VPN or proxy server might be blocking your requests. To ensure all functions on deepl.com are working, contact your IT department to check that the following domain pattern isn’t blocked by a firewall, VPN, or proxy server: *.deepl.com (deepl.com and all subdomains).
Clear cache and cookies

Reinstall the app
If your operating system is compatible with the above-mentioned requirements and you’ve ensured that you aren’t blocked by a firewall, VPN, or proxy server, but your desktop app still doesn't work, you can try to uninstall the DeepL app, and reinstall to make sure that you have the latest app version.
