# Helmut4 Client

The purpose of this guide is to assist you in upgrading the Helmut4 client to a newer version.

Updating the client is generally straightforward. On Windows, an uninstaller is available, which removes the client and the Helmut4-related extensions. 

Running the new client installer defaults to updating the client and the Adobe-Helmut4 extensions.

It is important to note that when updating Helmut4 and Adobe simultaneously, Adobe applications should be updated first; otherwise, the extensions will not be available.

For further information, please consult the [supported Adobe versions](/helmut4-releases/v4.7.2/getting-started/supported-adobe-versions.md) or [Helmut4 client tech specs](/helmut4-releases/v4.7.2/getting-started/installation-guide/helmut4-client.md).

**Update procedure: client - server**

*Please update the Helmut4 client on every workstation in advance.*

Note: Updating the Helmut4 server first may lead to compatibility issues, as the client might lack certain dependencies introduced as part of new features or changes.

### Helmut4: Server vs client version

Every stable/snapshot release has a dedicated client. The specific client version for the server can be found on the admin webpage or via API.
