Migrating to SAP GUI for Windows 7.40 will migrate the saplogon.ini to the new UI Landscape Configuration XML. Due to some bug, the SAP Router string will not be migrated successfully.
Therefore, manual action is required. Using some XML editor (like Notepad++ with XML Tools plugin), open the configuration file (“C:\Users\<Username>\AppData\Roaming\SAP\Common\SAPUILandscape.xml”), sort the XML using the XML Tools and edit the SAP Router strings removing the tailing “/H/”.
Save the file and relaunch the SAP GUI Logon Pad or SAP NetWeaver Business Client
