Double clicking an extensionless file in Dopus opens it in notepad.exe rather than my preferred notepad++. Ive been through the 'file types' dialog and replaced every instance where notepad is configured to open a file with notepad++ but it still opens with notepad. After some research on Technet I added the registry keys below and now it works correctly on Windows explorer but Dopus still insists on using notepad.exe. Any suggestions on how/where I could force this setting? I did try changing the action for the Dopus 'Unknown file type' but this didn't work either.
[HKEY_CLASSES_ROOT\.]
@=""
[HKEY_CLASSES_ROOT\.\shell]
[HKEY_CLASSES_ROOT\.\shell\open]
[HKEY_CLASSES_ROOT\.\shell\open\command]
@="\"C:\\Program Files (x86)\\Notepad++\\notepad++.exe\" %1"
