Reuters Config Files - Where do they go?

If you are using the Reuters RFA 6.x APIs to consume market data, you know that there are three config files that RFA needs to find. These configuration files are

  • appendix_a
  • enumtype.def

Usually, if you are running a console or WinForms application, you put these config files in the same directory as your executable.

However, what if you are running a Windows Service that uses RFA?

After some experimentation, we found that you need to store the files in these places:

  • Windows 32 - Put the files in c:\WINNT\system32
  • Windows 64 - Put the files in c:\WINNT\SysWow64

A service or an executable that uses RFA (the Marketfeed API, not the OMM API) uses 32-bit DLLs. This is because Reuters does not yet have 64-bit DLLs for RFA. Therefore, you need to use CorFlags.exe on a 64-bit Windows 2003 server in order to get your application to run.

  • corflags mydll /32BIT+

Thanks to the wonderful Procmon utility from SysInternals for helping us out with this issue.

I'm not sure if it works, but you may consider this Win32 API function,
