You would like to know how to manually configure Internet Information Services (IIS) to run a 32-bit application on a machine using a Windows 64-bit operating system.
The process described below only pertains to machines using a 64-bit Microsoft Windows operating system running Internet Information Services (IIS) 6.0 or 7.0.
IIS 6.0
IIS 7.0
The process described below only pertains to machines using a 64-bit Microsoft Windows operating system running Internet Information Services (IIS) 6.0 or 7.0.
When installing to a 64-bit operating system, the ACT! Internet Sync Service and ACT! Premium for Web require their respective application pools to be configured to 32-bit mode. This process is handled differently in IIS 6.0 and IIS 7.0:
- IIS 6.0: When configuring the application pools used by the web applications to 32-bit mode, this will set all application pools on the machine to 32-bit mode. If there are web applications that require 64-bit application pools, these applications will stop working.
- IIS 7.0: In IIS 7.0, you can configure each individual application pool to 32-bit mode, so that changing one pool to 32-bit mode will not affect the web applications that require a 64-bit application pool.

IIS 6.0IMPORTANT: In IIS 6.0, automatically switching to 32-bit mode will cause other Web applications on the computer to run in 32-bit mode. If those applications require 64-bit mode, they will stop operating; if not, they should continue operating as normal. However, they will have less RAM to access. Customers that require 64-bit mode for current Web applications will need to consider deploying separate servers dedicated to each compatibility mode for applications hosted on the server.
To install the Internet Sync Service for ACT! by Sage Premium 2009 (11.0) or ACT! by Sage Premium for Web 2009 (11.0) on a 64-bit version of Microsoft Windows, IIS must be configured to run application pools in 32-bit mode. You will receive a prompt to let the installer automatically perform the switch to 32-bit mode, but if Windows is ever re-configured to 64-bit mode and needs to be manually switched to 32-bit mode again, you will need to perform the following steps:
