Install 32-bit Exchange Agents on a Windows x64 Platform

Before You Begin

• Review the Installing 32-bit Components on a Microsoft Windows x64 Platform topic prior to installing the software.
• The following procedure utilizes the Multi Instancing feature. See Multi Instancing for an overview of this feature.

To install 32-bit Exchange Agents on a Windows x64 platform:

1. Install the first instance.

   This instance must contain the x64 agents, including the x64 Exchange Database iDataAgent (if applicable).

2. Create the bAllowMultiInstances and bAllow32BitInstallOn64Bit registry keys on the Windows x64 platform.

   Using Registry Editor incorrectly can cause serious problems that may require a reinstall of the operating system. Microsoft does not guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. You must also understand how to restore the registry if a problem occurs.

3. Install the second instance.

   This instance contains the 32-bit MAPI-based Exchange Agents.

The 32-bit MAPI-based Exchange Agent can now be used alongside the x64 Exchange Database iDataAgent.
