You have to copy your files to the Activation Server 4 with an FTP software (using the File Explorer will not work).
Using the popular FTP Tool FileZilla Client (http://filezilla-project.org/) the settings would be as follows:
The user name always starts with lp + number.
It is important to set the transfer mode to Active
After login you will see a directory structure similar to this one:
Select the folder ..alg and copy to this directory:
• All files from the folder ..\projectname\config\Web Activation Server\alg
Select the folder ..\pconfig and copy to this directory:
• All files from the folder ..\projectname\config\Web Activation Server\pconfig
Username and Password can not be changed
You have to restart the Web Service after making configuration changes.
