Remove Filerequest prompt to create new file

[pkonduru]

Hi All,

In my installer, one of my custom dialogs prompts the user to browse for a file with .lic extension. I am using nsDialogs with CoolSoft NSIS Designer.
After clicking on the browse button, my file browse window only displays files with .lic extension. If the user types in any random say "test.lic" in the Filename area, the file browse window prompts for "test.lic does not exist. Do you want to create it?".
How can I disable this ? Use should be able to only browse for files that exist.

Appreciate any responses.
