When a program is installed on a computer, an uninstaller is installed along with it, the purpose of which is to remove the program, all components created by it, and entries in the system registry. However, not all uninstallers are able to take into account the peculiarities of the hardware, software and operating system of your computer. As a result, attempts to uninstall such a program only generate error messages, leaving the program in the installed list.
Instructions
Step 1
In this case, the simplest solution would be to manually delete entries related to this program from the Windows registry. The first step in this procedure is to launch the uninstallation wizard - by right-clicking "My Computer", select "Add or Remove Programs" from the context menu. The same can be done through the control panel - a link to it is located in the menu on the "Start" button.
Step 2
It will take several seconds (sometimes several tens of seconds) for this utility to compile a list of installed software. When this is done, just minimize this window - in the future it will be needed as a reference for checking with the registry.
Step 3
The rest of the work will take place in the Windows Registry Editor - launch it. This can be done by right-clicking My Computer and choosing Registry Editor from the context menu. Or you can through the program launch dialog - press the key combination CTRL + R, enter "regedit" (without quotes) and press Enter.
Step 4
Whenever you edit the registry, be sure to make backups of its current state - open the "File" section in the editor's menu and click the "Export" item. A file save dialog will open - save the backup with a name that contains today's date. This will make it easier to find it if you need to restore the registry.
Step 5
After that, sequentially expanding the branches in the left pane of the editor, go to the Uninstall section. Your route should be like this: HKEY_LOCAL_MACHINE => SOFTWARE => Microsoft => Windows => CurrentVersion => Uninstall
Step 6
Now you will need the uninstallation wizard minimized to the tray - expand it, find the name of the program to be removed and look for a key similar to this name in the expanded Uninstall section of the registry editor. There should be a name in the left pane that is not exactly the same as the name in the uninstall wizard, but similar. When you find something similar, expand it and click the DispiayName parameter. It is from this parameter that the Windows uninstaller takes the names of the programs, making its own list, so here the name should be exactly the same. If not, look for another similar key and check the contents of its DispiayName with the name specified in the list of the uninstallation wizard.
Step 7
When a match is found, delete the key in the Windows registry. Please note that you need to delete not only the DispiayName parameter, but this entire registry key. Close the list of key parameters, right-click it and select Delete from the context menu.
Step 8
Close the uninstall wizard and reopen it so that the list of installed programs is updated in it, and you can make sure that the uninstalled program is no longer among the installed applications.
