It's a wonderful windows thing, and how it assigns system tray icons to programs.
The easiest way to fix that is to use the Uninstaller app (uninst-InnerSpace.exe) in the InnerSpace folder (after saving your Toolkit profiles somewhere else - File menu, Save As in the toolkit), to remove InnerSpace and then reinstall.
Or, you can also use the dev build of InnerSpace, which does something different with the icon registration to stop the stupidity of Windows from throwing such errors.
To try that, Right click Inner Space, select Patcher, select (it's a the red dot) the option for "Download development (test) patches"". Then right click Inner Space, select Exit. Reload Inner Space again, see if it that fixes it.
