Cannot add dll to 32-bit PowerShell - powershell

Question

I am trying to add the Exchange 2007 SnapIn for 32-bit Powershell (Microsoft.Exchange.Management.PowerShell.Admin) but I seem to be having some trouble when installing the dll file.
These are the commands I am running in order to register the SnapIns
PS C:\Program Files\Microsoft\Exchange Server\Bin> $snapinPath = 'Microsoft.Exchange.Management.PowerShell.Support.dll'
PS C:\Program Files\Microsoft\Exchange Server\Bin> C:\Windows\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe /i $snapinPath
The above works without issue. I then go to install the main SnapIn with the following commands:
PS C:\Program Files\Microsoft\Exchange Server\Bin> $snapinPath = 'Microsoft.Exchange.PowerShell.Configuration.dll'
PS C:\Program Files\Microsoft\Exchange Server\Bin> C:\Windows\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe /i $snapinPath
Microsoft (R) .NET Framework Installation utility Version 2.0.50727.5483

Exception occurred while initializing the installation:
System.BadImageFormatException: Could not load file or assembly 'Microsoft.Exchange.PowerShell.Configuration, Version=8.
0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. An attempt was made to load a program with an incorrect format..
I'm not sure what I'm missing here. It's a fresh Exchange 2007 install so nothing should be corrupt.

Answer 1

My issue was that I was using the 64-bit version of the Microsoft.Exchange.PowerShell.Configuration.dll.
I required the 32-bit version. As it did not allow me to install the 32-bit version, I extracted the setup files for the 32-bit version of exchange, and copied the setup\serverroles\common folder to C:\Program Files\Microsoft\Exchange Server, and renamed it to Bin32.
The final stage was to copy this registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.PowerShell.Admin
to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.PowerShell.Admin
and then change any paths within the key to point to the new Bin32 folder.
At this point, it should be possible to load the Microsoft.Exchange.Management.Powershell.Admin snapin into a 32-bit Powershell (Great for IIS apps which depend on 32-bit libraries).
