"Failed to create settings page" error when attempting to access "Translation Results Window" setting

Greetings!

I am in the process of setting up my initial settings for my first time use of Trados Studio, and when I try to access the "Translation Results Window" setting under "Editor", I get the error message "Failed to create Settings Page with the following details:

Could not load file or assmebly 'Sdl.DesktopEditor.Control.dll' or one of its dependencies. The specified module could not be found.

TYPE: System.IO.FileNotFoundException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b7aa5c561934e089

FILENAME: Sdl.DesktopEditor.Control.dll

SOURCE: Sdl.TranslationStudio.Editor

HRESULT: -2147024770

The error XML file looks like this

I checked, and the .dll file mentioned in the error exists in C:/Program Files (x86)/SDL/SDL Trados Studio/Studio15

I would appreciate advice on how to address this. Thank you in advance!
