That was exactly what i needed
but when i run the script to uninstall, its not identifying my application which has to be uninstalled
Even when i tried to retrieve all the programs, my concerned application is not in the retrieved list
You can only use this approach for installations that use Windows Installer. If this does not work for you, you can launch the application's uninstallation executable from TestComplete by using the WshShell.Exec method. You need to specify the full path to the executable as the method's parameter. Please refer to the following MSDN page to learn how to use this method: http://msdn.microsoft.com/en-us/libr...4a(VS.85).aspx
Then, you can complete the uninstallation process using key-presses, mouse movements and clicks.
