If you want to remove products from your computer, you should use the Windows control panel’s Add or Remove Programs dialog box for each product you want to remove. This uses the PowerBuilder setup maintenance program to remove:
Shared and standard program files
Folder items
Program folders
Program directories
Program registry entries
The setup maintenance program removes file and icon groups, as well as system and user path settings in the registry and INI files. These changes are not made if you simply delete directories.
The setup program increments the usage count in the registry for each shared Sybase 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.
To use the setup maintenance program to remove
a product:
Make a backup copy of any files you might want to reuse (such as DB, INI, and PBL files) if you plan to reinstall.
Open the Control Panel from the Start menu and double-click the Add/Remove Programs icon.
On the Install/Uninstall tab page, select the product to remove, click Add/Remove, and click Yes when prompted to confirm that you want to remove the tool.
If you are prompted to remove 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.
