Issue
When the NSISdl plugin must download a file, and there is no internet connection, the target file gets deleted if it already exists.
Cause
NSISdl deletes the target file if an error occurs, to prevent leaving any corrupted files.
Solution
Use the Dialer plug-in to check the internet connection.
Recommendation
You should download the file to a temporary directory (such as $PLUGINSDIR or $TEMP), and as soon as you've made sure that you've got the right file, and there were no errors, then you should copy it to its destination.
