Checking .NET 
Framework 
Requirements 
Before you use either the source-file directory or the silent install option, 
you must make sure that your system meets the minimum installation 
requirements.
Microsoft .NET Framework 2.0 includes the runtime and associated files 
needed to run BACS 3, and must be installed on your system in order for 
BACS 3 to operate. For information on the minimum and recommended 
.NET Framework versions for your operating system, see 
Table 14.
Note
You do not need to upgrade .NET for the Windows Server 2008, 
Windows Server 2008 R2, Windows Vista, or Windows 7 Operating 
Systems.
Note
For optimal performance of BACS 3, Broadcom recommends .NET 
Framework 2.0 SP1, .NET Framework 3.0 SP1, or .NET Framework 
3.5, depending on your operating system. 
Note
Starting BACS 3 without .NET Framework (version 2.0 or above) 
installed on your system results in an error.
