Update package

Updating the program package can only modify the program package name, workspace, executable file path, startup parameters, and synchronization type, and cannot re-upload the program package. If you need to update the application package, please select "Add New Version" on the program package overview page.

**Noun Explanations:**

- **Program Package Name:** Used to define the name of the program package, which will be filled in as the default name when adding an application.

- **Version Number:** The version number of the program package, used to differentiate different versions, and applications can switch to use different versions based on the version number.

- **Workspace:** Represents the workspace to which the application belongs, used to differentiate user permissions, access permissions, and the application concurrency limit under the workspace.

- **Executable File Path:** The relative path of the executable file that starts the application in the compressed package, which will be automatically filled in the dropdown list of executable file paths after uploading the program package.

> **Special Note:** For applications developed using the Unreal Engine, when uploading the application, please do not choose the exe program in the root directory. The correct path should be: "Same level directory -> Project name same directory -> Binaries -> Win64 -> xxx.exe". An example of an executable file path is: **WindowsNoEditor\MyProject3\Binaries\Win64\MyProject3.exe**

- **Startup Parameters:** For applications developed using the Unreal Engine, startup parameters may be required. You can view the command line parameters by directly running locally -> Start Task Manager -> Details -> Place the mouse over the status bar, right-click and choose "Select Columns" -> Check "Command Line", then find the running UE4 application and view the command line parameters.

- **Synchronization Type:**

> **Active Sync:** Once the application or rendering node is registered, the application is synchronized directly and can be used immediately.

**Semi-Active Sync:** When selecting semi-active synchronization, you can choose a synchronization area. The default synchronization coefficient is 1, indicating that only one node is synchronized for one application in a region. This scenario is suitable when multiple cluster nodes have insufficient disk space, and only synchronizing one node can save disk space.
