I have a WPF application that I am using to scan documents to a users mailbox etc.
When debugging the application on my 32bit Windows 7 professional machine all goes according to plan, as well as the deployed version on another 32bit Windows 7 machine.
When I deploy to a XP machine and try to start a scan I get the following error:
Retrieving the COM class factory for component with CLSID
{850D1D11-70F3-4BE5-9A11-77AA6B2BB201} failed due to the following
error: 80040154 Class not registered (Exception from HRESULT:
0x80040154 (REGDB_E_CLASSNOTREG)).
Any suggestions?
The win 7 version does not work on xp - you could try downloading this version for XP.

To make deployment simpler, turn the files from Richard Friend's Answer into an Inno installer.

I just did that since I have to deploy this in a small office and it works. I'm putting it on x86 machines only. You might have to tweak it a bit to work on x64 machines.
