DD Installer is complaining that my IIS does not support 32-bit enabled apps

When i try to install the DynamicDirectory 2.0.x it is complaining that the IIS is not setup for running applications in 32-bit mode.

That is odd, because the server is 2003 32-bit.

How do i fix this ?

We do not know what causes the 32-bit mode flag to be unset.

But you can fix it quickly, by running this command from a prompt.

This fix also applies to 64-bit machines.

Configuring IIS to Run 32-bit Applications on 64-bit Windows (IIS 6.0)

Windows Server 2003TM, Service Pack 1 enables IIS 6.0 to run 32-bit Web applications on 64-bit Windows using the Windows-32-on-Windows-64 (WOW64) compatibility layer. IIS 6.0 using WOW64 is intended to run 32-bit personal productivity applications needed by software developers and administrators, including 32-bit Internet Information Services (IIS) Web applications. For more information about running 32-bit applications on 64-bit Windows, see Running 32-bit Applications on 64-bit Windows.
To enable IIS 6.0 to run 32-bit applications on 64-bit Windows

1. Open a command prompt and navigate to the %systemdrive%\Inetpub\AdminScripts directory.

2. Type the following command:

cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 1

3. Press ENTER.

Then run the installer again.
