Hi,
Automise build 3.0.739
Im trying to install a new licens on my evaluation version.
When I try to install via Help-\> "Install license key" and browse to the key it is not possible to choose the key in the browser. In the "File og type" i can only use "License Files".
The License key has the extension .xml but i look like the browser cannot see the extension type (.xml).
Why can I not choose the key?
Best regard
Gordon

Change the file extension of the license file so that it is .license - some browsers (IE 6 in particular) insist on changing the file extension when downloading the files from our website.
