Hello,
 
I'm a brand new user of OpenEV.  I need to export a sid file to ecw.  I've selected Export from the File menu.  In the GDAL Export tool  dialog box I've chosen the input file and entered an output file with ecw extension.  I set the output format to ECW.  When I click the Export button nothing happens.  I checked the output location and the file is not there.  How can I do this?
 
I'm using Windows 7 Pro 64-bit.
 
thanks
