OCSCore.msi does not have a redistribution license and must be installed only by installing the Admin Tools available on the Microsoft Office Communications Server 2007 R2 DVD.

For detection, the application bootstrapper should make use of the upgrade code and MinVersion value of OCSCore.msi. If appropriate values of upgrade code and MinVersion are not detected, the application bootstrapper should fail and should suggest that the administrator install OCSCore.msi using Office Communications Server 2007 R2 Admin Tools.

OCSCore upgrade code = E69B354B-B22C-4595-BA36-BF390CF37711

When you run the Microsoft Unified Communications Managed API 2.0 SDK setup application (SetupUCMASDK.exe) to install the UCMA 2.0 Core SDK, and do not specify a different location, a directory named %Program Files%\Microsoft Office Communications Server 2007 R2\UCMA SDK 2.0\UCMACore\Redist\is created.The following files are in this directory.

• UcmaRedist.msi
  
  
• WmaCheck.wxi
  
  
• wmfdist64.exe
  
  

If you run the Microsoft Unified Communications Managed API 2.0 SDK setup application (SetupUCMASDK.exe) to install the UCMA 2.0 Core SDK on a 32-bit development environment, the 32-bit version of Microsoft Unified Communications Managed API 2.0 Core Redistributable (UcmaRedist.msi) is installed, but this version is not supported. Application development using Microsoft Unified Communications Managed API 2.0 SDK on 32-bit client platforms along with 64-bit client/server platforms is supported.

When Microsoft Unified Communications Managed API 2.0 Core Redist (UcmaRedist.msi) is installed, it determines whether Microsoft .NET Framework Version 3.5 SP1 Redistributable Package and Microsoft Visual C++ 2008 Redistributable Package are already installed. If not, UcmaRedist.msi displays a warning message.

Whenever you deploy an application that is built on the UCMA 2.0 Core SDK, Microsoft Unified Communications Managed API 2.0 Core Redistributable (UcmaRedist.msi) must be present as a prerequisite on the server computer on which it is deployed. The recommendation is that your application bootstrapper should check for the presence of UcmaRedist.msi and the installation should fail if it is not present.

The upgrade code and minimum version code for the Microsoft Unified Communications Managed API 2.0 Core Redistributable (UcmaRedist.msi) for a 64-bit deployment platform are as follows.

UcmaRedist.msi upgrade code = 7CA5F91F-26AA-42f9-AB67-B85371B1D5E0

For detection, the application bootstrapper should use the upgrade code and MinimumVersion values of UcmaRedist.msi. If the appropriate values of the upgrade code and MinimumVersion are not detected, the application bootstrapper should fail and should suggest that the administrator install UcmaRedist.msi.

If you use Microsoft Unified Communications Managed API 2.0 Core SDK to develop applications such as notification applications, IVR systems, and Automated Call Distributor systems that will play or record media, your application must have the Windows Media Format Runtime.

If you use WiX to build your application installer, you can use WmaCheck.wxi in the Redist directory to detect Windows Media Format Runtime by including WmaCheck.wxi in your installer, as follows: “<? include WmaCheck.wxi?>”. When you run the application installer on a system that does not have Windows Media Format Runtime, one of the following error messages is displayed.

If an error occurs and you have the Microsoft Office Communications Server 2007 R2 CD, follow the instructions from there to install Windows Media Format Runtime. Alternatively, you can install Windows Media Format Runtime as described in the following table.

If you do not use WiX to write your application installer, an installer running on either Windows Server 2003 or on Windows Server 2008 can detect the presence of Windows Media Format Runtime by verifying that wmvcore.dll is in the %windir%\system32 directory and that its version is greater than or equal to 9.5. If your installer detects that Windows Media Format Runtime is missing, use the previously described steps to install it.
