Release Notes
Build 105.1
This build addresses a number of significant issues
including:
-
Upgrades the projects to VS2008
- Fixes the conflict
between x64 and x86 versions of OpcEnum
- Adds a .NET RCW that supports the
x64 and x86 platforms (MSIL compliant)
- All source code is installed in
the $(LocalAppDataFolder) instead of $(ProgramFiles)
On x64 systems the components install a new component
called the Category Manager. This component makes x64 servers visible to x86
clients.
The x64 version of the Core Components Redistributables installs
the 32bit versions so it is the only package that needs to be installed on x64
systems.
The OpcComRcw.dll replaces all of the OpcRcw.*.dlls. However, the
old DLLs are still installed for backward compatibility.
The Merge Modules
install the development environment if the OPC_INSTALL_SDK property is set.
The installers no
longer try to detect the presence of Visual Studio. The SDK package always installs
the development environment.
All .NET assemblies are placed in GAC and
$(ProgramFiles)\Reference Assemblies\OPC Foundation directory (the latter only
for the development environment install).
All C++ headers and
typelibs are placed in $(CommonProgramFiles)\OPC Foundation\Include. The
x64 versions are in the 'x64\Include' directory.
The SDK package installs
the Merge Modules in the $(CommonProgramFiles)\Merge Modules directory.

System
Requirements Requirements
Operating Systems
The Core
Components binaries (excluding merge modules and installers) support the
following operating systems:
Windows 95 with DCOM95;
Windows 98 with DCOM98;
Windows ME;
Windows NT;
Windows 2000;
Windows XP;
Windows Server 2003;
Windows Vista;
Windows 7
The
installers have only been tested on Windows XP and Windows 7 at this
time.
Installers
The
installers come with a setup.exe file. This is the file that must be used to
install under Windows Vista. Double clicking on the MSI will cause an error.
The
installer packages are self-installing files; however, they require that
Windows Installer 2.0 be present on the system (it is standard on Windows
2000 SP3 and Windows XP). The Windows Installer 2.0 support files for other
operating systems can be downloaded from Microsoft's website at:
Download Windows Installer 2.0
Redistributable for Windows NT 4.0 and 2000
Download Windows Installer 2.0
Redistributable for Windows 95, 98 and ME
The installers
automatically check if the .NET framework is installed on a particular
system; if it is not found the .NET components are not installed.
Source Code
All source code projects require Visual
Studio 2005 with Service Pack 1 installed.
The service pack can be downloaded here.
Installation
Redistributable
All
COM servers and proxy/stub libraries that have been previously released are
installed in the system folder and reference counted in order to ensure
compatibility with older install programs. New COM servers and proxy/stub
libraries are installed in the common files folder under "OPC
Foundation\Bin ".
Shared
.NET assemblies are signed with the OPC Foundation's master key-pair and
installed in the Global Assembly Cache (GAC). The source code distribution
includes a test key-pair that permits developers to experiment with the
assemblies without affecting other vendor's applications.
Vendors
may install these assemblies in a vendor specific directory, but the vendor
needs to recognize that .NET framework will look in the GAC for an assembly
before probing the vendor specific directory. As a result, applications
will use the assemblies in the GAC even if a vendor has installed copies in a
vendor specific directory.
Vendors
who wish to always use their private versions must re-sign the assemblies
with their own key pair and build their applications against these re-signed
assemblies. This approach will not impact other applications that were built
against the OPC Foundation signed and versioned assemblies.

Problem
Reporting
As part
of a broader initiative to increase adoption of OPC specifications and to
improve service to members, the OPC Foundation intends to maintain binaries
and sample code over time following a model similar to Open Source projects.
Vendors are encouraged to report problems, bug fixes, enhancements and any
other comments about the components supplied by the OPC Foundation. To
support this effort, the OPC Foundation has technical staff prepared to
review and incorporate feedback into the baseline and release new versions of
the components and sample code in a timely manner for the benefit of all
members.
Please
note that this support is intended for OPC Foundation members who are
incorporating OPC support into their products.
Problems
related to a particular download should be posted to the appropriate group on
the OPC
Foundation Message Board.
