As the licensing algorithm was changed in Softros LAN Messenger version 4.5, any license file ("license.lic") received before November 10, 2010 needs to be updated to be compatible with this and future versions of the program. This page allows you to check and update your old license file.
You can find the old license either in your inbox or on your computer's hard drive. It should be located in the folder where Softros LAN Messenger is installed (by default, C:\Program Files\Softros Systems\Softros Messenger).
If you have more than one license file and need them combined, cannot find your license, or experience other difficulties, please contact us through the technical support form for prompt assistance.
