First Steps
You know how KOSMA updates itself and how to check whether your version is up to date.
KOSMA checks for updates when it starts and every 60 minutes, downloads them and restarts to install them.
In the **Help** menu, click **Check for Updates**. You can also do this in the sign-in window.
KOSMA shows every update message at the bottom right of the [Project Manager window](/kb/article/the-project-manager-window). Before you sign in, this is the sign-in window.
If you already have the latest version and checked from the menu, KOSMA shows this message:
KOSMA {version} is up to date.
On macOS only, KOSMA shows this message just before it downloads an update:
KOSMA {version} is available and will be installed automatically.
After the download, KOSMA shows this message on macOS and Windows:
KOSMA {version} is ready — the application will restart in a few seconds to apply the update.
Five seconds after the restart message, KOSMA restarts.
If a project has unsaved changes, KOSMA stops the restart and shows the **Unsaved changes** dialog.
With **Discard All**, the unsaved changes of every listed project are lost.
| Button | What KOSMA does | | --------------- | ------------------------------------------------------------------------ | | **Save All** | KOSMA saves every listed project and restarts. | | **Discard All** | KOSMA discards the unsaved changes of every listed project and restarts. | | **Cancel** | KOSMA does not restart. Nothing is lost. |
After **Cancel**, KOSMA offers the update again at the next hourly check, or earlier when you start KOSMA again.
The check fails, for example, when there is no internet connection. KOSMA then shows an error message. On macOS, it reads:
Update failed: {error}
On Windows, it reads:
The update check could not be completed. Please try again later.
KOSMA also shows these messages when an automatic check fails. Check your internet connection and click **Check for Updates** again.
When the KOSMA server stops supporting an older version of the app, that version can no longer connect. KOSMA then works offline and shows your local data. Your edits stay on this computer. Version 1.232.11 cannot show the reason. Instead, it shows two error messages with the code KOSMA-E-0000. They disappear after the update, so you do not need to report them.
After the update, KOSMA connects again and sends your edits. To update at once, click **Check for Updates** in the **Help** menu.
