I have Keypass from many time, now I work with 1.17. With double click on URL field always have the message: "impossible to find such file" . This is my transalation from italian. I have Win Xp sp3 and Mozilla Firefox.
Try copying the URL from KeePass into the Windows Run dialog (Win+R). Does it work from there?
Doing so, I get the same error message
Works for me with this address in the URL field: http://keepass.info/
Do you have "URL-Override: " in the Notes field? Try taking it out.
No url works with double click. There is a way to communicate the browser address in the option ?
Since the problem also occurs when you enter the string (URL) in the run dialog, the problem is not with KeePass. There is a problem with the string itself, or it refers to a program or file that doesn't exist, or Windows doesn't know how to handle the string (e.g. a default browser is not registered with Windows).
Chances are there is no default browser registered on your computer. Start your favorite browser, and if it doesn't prompt to become the default browser, make it the default browser in its settings.
You are wright, in the option of Firefox I set Mozilla as default browswer and it works.
