To update an existing Activation Server version 2.5.x copy the following files

- ..\alg\autolicgenerator.exe to the same folder on the activation server
- ..\bin\lpweb.dll to the same folder on the activation server
- copy your licprotector.lic file from your Licence Protector installation, version 2.6 (important must be version 2.6!), to the activation server to the folder ..\alg
- restart the web service

Note: The version on the Activation Server administration interface does not change to version 2.6. All new installation codes from version 3.6 are supported with 
this update.
