Directory Opus Open With menu + SumatraPDF. Error

I'd say this is the problem:

HKCR\SumatraPDF\shell\open\command: "" is REG_SZ:
    ""C:\Program Files\SumatraPDF\SumatraPDF.exe" "%1" %*"

HKCU\Software\Classes\SumatraPDF\shell\open\command: "" is REG_SZ:
    ""C:\Program Files\SumatraPDF\SumatraPDF.exe" "%1" %*"

HKLM\Software\Classes\SumatraPDF\shell\open\command: "" is REG_SZ:
   ""C:\Program Files\SumatraPDF\SumatraPDF.exe" "%1" %*"

The "%1" %* on the end means:

  • "%1" -- add the first selected file path in quotes, then...
  • %* -- add all selected file paths (including the first path again).

I think that string in the registry should only have one of those, not both.
