Copy your license files DGMR.LIC and DGMR.LICX to the iNoise program folder (usually C:\Program Files\DGMR\iNoise 2017\). In case the software still shows <unregistered user>, this is probably caused by the secured Windows environment. Windows won’t allow files to be copied directly from an email message to a secure folder, such as the “Program files” folder. To copy the license files from an email message, you should copy them first to a temporary location, for instance your desktop, and from there you can copy them to the iNoise program folder.
