No dialog Box

I just downloaded KODI 16.1 to my HP laptop. I am operating Windows 10, Intel i5, 8 GB Memory. I went to the File Manager to Add Source, nothing happens when I click. No dialog box appears. I click on Add Root, same thing, nothing. Doesn’t matter if it is A or B. No dialog box appears.

Please help. My Kodi is totaly empty because of this.
