Error Code

Resolve server configuration and synchronization problems using diagnostics, command validation, and client setup verification.
Adobe Update Server Setup Tool (AUSST) setup, sync, or client deployment fails, and the log files or command-line output show an error code, such as 4: Network failure, 7: Output disk full, or 9: File not found on server. Use the following tips to identify the cause and resolve the issue.
Before you begin
- Ensure the web server runs correctly. Verify your internal update server. If not, apps and updates might get downloaded from the Adobe Update Server (AUSST does that automatically), but will not be distributed to clients.
- Ensure no network connectivity issues prevent the internal update server from connecting to the Adobe update server. For example, check that you can access the default welcome page of the internal update server.
End users see the following error if the Creative Cloud Desktop App is unable to connect to your internal update server (AUSST):

Command syntax errors
Remove extra spaces in commands
Extra spaces in AUSST commands cause parsing errors and command failures, for example:
- Correct: --root=/update/folder
- Incorrect: --root = /update/folder or --root= " /update/folder"
Review the AdobeUpdateServerSetupTool command syntax.
Remove spaces between parameters and =
Remove spaces between the = sign and arguments.
Remove spaces within file paths, for example, between quotation marks and slashes.
Ensure no trailing spaces exist at the end of the command.
Specify full URLs with protocol and port numbers
The URLs for the server should include the protocol (such as http://). Incomplete URLs in the AdobeUpdater.Overrides file prevent proper server communication. For example:
- Incorrect: <URL>/Adobe/CS/webfeed/oobe/aam20/win/</URL> — missing the http:// protocol
- Correct: <URL>http://serverabc.example.com/Adobe/CS/webfeed/oobe/aam20/win/</URL>
If the port number differs from the default value of 80, specify it separately, for example: <Port>1234</Port>
Review the AdobeUpdater.Overrides or configuration files.
Verify all server URLs include the protocol (http:// or https://).
Add port numbers if different from the default port 80.
Save the configuration file.
Ensure the server location has write permissions
Ensure that you have the write permissions for the server location where the apps and updates are to be stored. The lack of it prevents successful sync, resulting in an incomplete server setup.
Use absolute paths in all commands
Avoid relative paths in commands because AUSST requires absolute paths for all file locations. Review all path parameters in your AUSST command.
Client configuration issues
Generate the correct client configuration files
The client configuration files are generated at a location determined by the --genclientconf parameter of the AdobeUpdateServerSetupTool command. For more details, refer to Generating client configuration files. Two files are generated, one each for Windows and macOS clients. Check that the files are available in the respective locations on the internal update server.
Deploy the correct client configuration files to the correct location on the end-user’s computer
After the client configuration files are generated on the internal update server, they are deployed on each end-user computer. The files are different for Windows and macOS.
The location for the file on each end-user computer is platform-specific. Ensure that the configuration files are deployed on the end-user computers at the locations.
Sync and update issues
Perform a fresh sync for duplicate apps
In exceptional cases, multiple copies of the same app or update appear on client computers when using an incremental sync mode. When deployed, the users will see multiple copies of the packages on their computers. Fresh sync ensures the internal update server has a single and correct copy of all packages.
Run a fresh sync instead of an incremental sync using the execute command: AdobeUpdateServerSetupTool --root="<update folder>" --fresh
Wait for the complete download to finish.
Verify that only single copies of apps exist on the server.
Test deployment to a client machine.
Run a fresh sync if the error persists
Persistent errors may occur during an incremental sync despite trying other troubleshooting steps. Fresh sync downloads all updates from Adobe's servers, resolving corruption or incomplete download issues.
Stop any running AUSST sync processes.
Run a one-time fresh sync: AdobeUpdateServerSetupTool --root="<update folder>" --fresh
Monitor the download progress and check for errors.
Review logs after completion.
