Hello, please see whether this way can help you:

Well, if you know how to work with the windows registry, you probably can perform a manual force uninstall.

Before I go into detail about how to do this manually, I'd like to say that this is pretty advanced stuff, and if you're not a power user, then perhaps you should consider using specialized software such as the Perfect Uninstaller which allows you to do this in just a few clicks.

If you are a power user, then let's continue. First, let's see how to remove the program from the list of installed programs. To do that you need to open the registry browser:

1.Click Start and choose Run in the menu (If you're using Windows Vista then press Win+R on your keyboard).
2.Type regedit and hit Enter.
3.On the left side is the registry settings tree, use it to go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
4.Inside that key you'll find a lot of keys that belong to different programs. Some are named after the program's name, others as a mix of numbers and letters that makes no sense. Look through each of them until you find one that has the key DisplayName (on the right) with your program's name in it.
5.Notice the key UninstallString - this key points to the uninstall program, and the log file usually resides in the same folder as that program.
6.If you delete the key in which you've found the DisplayName key with the value equal to your program's name, then your program won't appear on the Add/Remove programs list.
Some programs create new entries in the registry to store their configuration options, these entries can usually be found in the HKEY_CURRENT_USER\Software or in HKEY_LOCAL_MACHINE\SOFTWARE - look for the program name or the name of the company that made the software. Don't delete Microsoft though - that contains Windows settings as well.

Next we have to find all the files that have been copied. Open the folder in which the uninstall program should be, and look for files which are named uninstal.log or setup.log or something similar. The list of files that have been installed is inside this file, you can open it in your notepad and find all of the files that have been copied onto your system. Delete the files and you'll get rid of the program almost fully.
