Download - Latest Userkey File
Download the latest Lin4Win licence key file to allow your copy of the software to work with all currently licensed LA100 units. This is not needed for MiniSonic or DigiSonic units as they are all supplied with a software licence.
Once you have purchased a license your unit's serial number will be included in the userkey file. This flexible system allows you to enable any computer, anywhere, anytime for use with any registered units.
Download the key file using the link above and save to C:\Program Files\Lin4WinXP\UserKey.dat or click 'Download UserKey' from the 'Online' menu in Lin4WinXP.
