Installation - Companion - Windows

Download and verify

Also download checksums.sha256. Compare the file SHA-256 with the line bearing its exact name before installing.

SHA-256 checksums

Connect the browser

Install the PrivCloud browser extension. Keep its exact ID from chrome://extensions or edge://extensions.

Install the extension

Extract the archive

Place the files in a permanent folder. Keep privcloud-companion.cmd and privcloud-companion.mjs together and check that node --version reports at least 20.

Download the registration helper

The portable archive does not contain this helper. Download it here and place it in the same folder. Its checksum is available in the helper checksum list.

Windows helper

Connect Chrome or Edge

In this folder, open an administrator PowerShell to create the shared registration folder. The browser registration uses the current user profile. Replace the path and both IDs with your actual values.

powershell.exe -ExecutionPolicy Bypass -File .\register-native-messaging-0.1.4.ps1 -CompanionPath "C:\PrivCloud\privcloud-companion.cmd" -ChromeExtensionId "CHROME_ID" -EdgeExtensionId "EDGE_ID" -Scope CurrentUser

Check that it works

Return to Integrations, select Refresh and check that the extension and Companion are detected. Sign in and try importing a small WebDAV file using a revocable app password.

Need help?

If Companion is missing, check Node.js, the launcher path and the extension ID, then reload the extension and PrivCloud. After an NVM update, configure the Node.js path again. A Flatpak browser may need explicit access to the Companion folder.
