SAP GUI for Windows 7.60 Changed Features:
Not supported for saplogon.ini and related configuration files
As of SAP GUI for Windows 7.60, the old configuration format for SAP Logon entries (saplogon.ini, sapmsg.ini, saproute.ini) is no longer supported by SAP GUI for Windows. SAP GUI for Windows can still handle this old format for compatibility reasons, because there may be external applications needing this old format, but using SAP GUI for Windows 7.60 with the old format is not supported. Therefore, all installations of SAP GUI for Windows 7.60 and newer must use SAP UI Landscape.
Changed integration with SAP Business Client
If SAP GUI for Windows and SAP Business Client are installed together, the SAP Logon (Pad) Desktop icon and the Business Client Desktop icon are installed. Additionally, file associations for SAP Shortcuts are created for both SAP Logon (Pad) as well as SAP Business Client. When starting an SAP Shortcut, the user can decide which program to run. With this, the old installation component Install SAP GUI Desktop Icon / Shortcuts even though SAP Business Client is installed is obsolete.
