Hello SouthCarolinaBo,
Are you trying to open this from a shortcut of Windows Explorer? If so, then you may need to fix it's target to point to %windir%\explorer.exe.
Does Windows Explorer open if you run the C:\Windows\explorer.exe file directly? You can type explorer.exe in the Start Menu search box and press enter for this.
Do you have any issues when trying to open other shortcuts or exe files?
