Hi!
When I tried to update Comodo Dragon 45.6.11.385 portable, I went to menu >> about (chrome://help), then with the message “A new version of Comodo Dragon is available” I clicked on Download. OK, I could see that it was downloading. After that it showed a message: “This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel.” so I could not update it. I am using Windows 10.
I Solved by downloading and reinstalling Comodo Dragon 46 manually. After downloaded 46, install as portable, I went to menu >> about (chrome://help), it showed me 45.8.12.389. So I clicked on Download and now it worked without that message, updating to 46.9.15.424.
OK, it updated to 46, but Comodo Dragon would be good update directly…
I was thinking about history, my personal settings, etc but when it is connected on Google account it is all restored.
I just create this post case some one face the same (specially that message).
Bye
