If you are having problems installing or using the DeepL app for Windows, check that you have adjusted your proxy server settings correctly. For more details on how to do this, see this Microsoft support article.
If your proxy server requires authentication (username and password), you can try setting it up as described in this Microsoft forum post.
If this doesn't work, you can specify the proxy settings for the installation process via Windows PowerShell. Open PowerShell in the folder where DeepLSetup.exe is saved and run the following commands:
$env:http_proxy="http://your.proxy.server/" $env:http_proxy_user="yourUserName" $env:http_proxy_pass="yourPassword" .\DeepLSetup.exe
After the installation, you may also have to configure the proxy in the app settings.
More information on the location of DeepLSetup.exe can be found in this article.
