Required Environment for Group Chat Installation

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

Group Chat also requires the following software components:

  • Microsoft .NET Framework 3.5 SP1

  • Microsoft Visual C++ Runtime 2 (Versions 2.0.50727.761 and earlier are not supported.)

If Microsoft Visual C++ Runtime 2 is not present on the computer, the Group Chat installation program installs it during installation. If Microsoft .NET Framework 3.5 SP1 is not on the computer, the user is prompted to download and install it before proceeding.
