Extension Error - ShellExecute failed (2) when "right click open with"

[Dan Comber]

Trying to open the change.log file using the right click menu but am getting an error.
Happening with all files I try. Error as below:

Notepad++ Extension: Error
ShellExecute failed (2): Is this command Correct?
“C:\Program Files (x86)\Notepad++\Notepad++.exe” “C:\Program Files
(x86)\Notepad++\change.log”
