When you run the AdobeUpdateServerSetupTool command, ensure that there are no spaces in the following cases:

• Between parameters and the = sign
  
• Between the = sign and arguments
  For example, the following command has an incorrect extra space between --root and the = sign

• Anywhere in a path.
  

For example, the following command has an extra space between the quotation mark (") and the forward slash (/)

The URLs for the server should include the protocol (such as http://). If the port number is different from the default value of 80, the port number should also be specified.

For example, the following section in the AdobeUpdater.Overrides file is incorrect because it does not specify the http:// protocol:

<URL>/Adobe/CS/webfeed/oobe/aam20/win/</URL>

<Port>1234</Port>

Note that in this example, the port number (1234) has been specified, which is required if the port number does not have the default value of 80.

Ensure that the location on the server where the apps and updates are to be stored has the correct write permission. Otherwise, apps and updates might not be synced/downloaded on the internal update server. The server setup process is not complete unless all apps and updates are synced/downloaded on the internal update server.

Check that the paths provided to all the command-line options are absolute paths. AUSST does not support relative paths.

In exceptional cases, multiple apps/updates of the same package might get stored on the internal update server if the option of incremental update sync is specified. These will then be deployed to the end-user computers, and the users will see multiple copies of the packages on their computers. If this happens, perform the fresh update sync (one time) by running the following command:
AdobeUpdateServerSetupTool --root="<update folder>" --fresh

This ensures that the correct single copy of the packages get downloaded to your internal update server, from where they are deployed to the end-user computers.

If you are using the incremental sync option and continue to get errors even after trying all the previous steps, perform fresh update sync (one time) by running the following command:
AdobeUpdateServerSetupTool --root="<update folder>" --fresh

This will ensure that all updates from the Adobe update server are downloaded to your internal update server.
