If you want your VEB application to use the SourceSafe Automation interface, you need to have 
Microsoft Visual Source Safe application version 6.0 or higher installed on your local system. 

In addition if you want to use such functionality as "View" and "Show differences" for SourceSafe files,
you need to register the file DiffMergeCTL.ocx (typing "RegSvr32.exe DiffMergeCTL.ocx"), and then set a 
reference to the DiffMergeCTL ActiveX Control Module. 
The file DiffMergeCTL.ocx must be placed in the same folder as the file ssus.dll (…\VSS\WIN32 by default). 

Note for Win95 users.
You may need to install Win95 upgrade to Win32 TCP/IP socket. In order to do that run W95ws2setup.exe. 
The patch programm can be found in same AMItools folder. 
Service is used by VEB.EXE to access remote (over TCP/IP protocol) servers
