Exported COM+ Proxy fails to install on 32-bit clients

Support for Windows Server 2003 ended on July 14, 2015

Microsoft ended support for Windows Server 2003 on July 14, 2015. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

Consider the following scenario. You have a Serviced Component complied for any CPU type, and you use a 64-bit installer to register it on a 64-bit version of Microsoft Windows. When you try to export this application you will produce an MSI file which can only be installed on another 64-bit system. If you then run the MSI on a 32-bit Windows client, you will receive an error message similar to the following:

This installation package is not supported by this processor type

More information
This behavior is by design. Use one of the following options to work around this behavior:

  1. Create your own MSI installer package for the 32-bit clients.


  2. First register the Serviced Component using the 32-bit version of regsvcs.exe, then make the configuration changes to the application, and then export the proxy; this will produce a MSI that will install on 32-bit machines. Later you may delete the application and instead register the serviced component using the 64-bit regsvcs.exe.
