Hi,
You may be best navigating back to the software's folder in Program Files in your main drive (Normally C:), to see if you can run its Uninstall program from there but it will most likely produce the same error.
There are a few routes from here for uninstalling the software from deleting the software folders and removing any registry files, to seeing if we can install the software again to fix it, so we can then uninstall it
Let me know,
