Uninstalling PowerBuilder

This topic describes how to uninstall PowerBuilder.

When you start to uninstall PowerBuilder, you will be asked to deal with the license first:

  • If you are using an online license, when you uninstall PowerBuilder with Internet connection, you will be automatically logged out PowerBuilder when the uninstall process starts; when you uninstall PowerBuilder without Internet connection, you will be prompted to contact your license administrator to de-activate your license on the website and then the uninstall process starts.

  • If you are using an offline license, you can uninstall PowerBuilder without deactivating the license (if you want to continue using the license on this computer), or deactivate the license and uninstall PowerBuilder (if you want to move the license to a different computer).

For how to log out PowerBuilder or deactivate an offline license, refer to Log out or De-activating an offline license.

Use one of these methods to run the setup maintenance program for the product that you want to uninstall:

  • Add or Remove Programs dialog box

    1. Make a backup copy of any files you might want to reuse (such as DB, INI, and PBL files) if you plan to reinstall.

    2. Open the Control Panel from the Start menu and double-click the Add/Remove Programs button.

    3. On the Install/Uninstall tab page, select the product to uninstall, click Add/Remove, and click Yes when prompted to confirm that you want to uninstall the tool.

    4. If you are prompted to delete a shared file, click the appropriate response.

      If the usage count for a system file in the registry indicates that the file is no longer being used, the setup maintenance program asks if you want to delete the file. Some applications do not increment the usage count; therefore, do not delete a file unless you are sure it is not being used by another application.

  • Silent uninstallation

    See the section called “Silent Install Commands”.

The setup maintenance program removes:

  • Shared and standard program files

  • Folder items

  • Program folders

  • Program directories

  • Program registry entries

The setup maintenance program deletes file and icon groups, as well as system and user path settings in the registry and INI files. Simply deleting directories does not fully uninstall these products.


The setup program increments the usage count in the registry for each shared Appeon DLL and each shared system DLL. The setup maintenance program decrements that count. The setup maintenance program does not try to delete a shared DLL until the usage count reaches zero.


Unlike the setup program, the setup maintenance program has no Back or Cancel button. Once you click Yes in the procedure below, the program cannot be stopped.
