Currently we have a testing server which is 32 bit and Production server is 64
bit.
and DTSearch engine DLL version: 7.61.7769.1 installed on both servers.

Scenario:
We have .Net Wrapper DLL which we compiling with AnyCPU option as we have to use
this DLL on 32 bit as well as 64 bit cpu.
Now we have added a reference of dt search DLL (i.e dtengine64.dll) in wrapper
.Net DLL . when we run this on 32 bit testing server it works fine, but when we
run the same DLL on 64 bit cpu
it is giving below error message


Error Details:

Error Message: Retrieving the COM class factory for component with CLSID
{A967E5D2-B0E1-11D3-B57C-00105AA461D0} failed due to the following error:
80040154.



Can you please suggest what we are missing.

Searching on the web revealed that we may have to complile the .net wrapper with
x86. We would like to keep the ANY CPU option since we want the .net wrapper DLL
to run 64 bit on 64 bit servers and 32 bit on 32 bit server.
