The PowerBuilder PBSHR110.DLL system library is locked by IIS when you run a Web Forms application. This prevents you from uninstalling PowerBuilder when PowerBuilder and IIS are installed on the same computer. To avoid disrupting other applications using the IIS server, PowerBuilder does not automatically shut down and restart the server. Even if the Web Forms application is run from a browser on a remote computer, you must shut down the server manually before you can uninstall PowerBuilder on the IIS server. [CR 441626]
