Datafeed Toolbox error using Thomson Reuters Eikon Desktop

Hi there

I have Thomson Reuters Eikon Desktop 4.0 installed and get the following error when using the datafeed Toolbox

>> c = treikon

Error using treikon
Message: Could not load file or assembly 'file:///C:\Program Files (x86)\Thomson Reuters\Eikon\Interop.EikonDesktopDataAPI.dll' or one of its dependencies. The
system cannot find the file specified.
Source: mscorlib
HelpLink:

This dll is not in the directory but EikonDesktopDataAPI.dll is, does the treikon function need to be amended for this?

Thanks

Peter

Am calling it from 32-bit Matlab, but thanks for the comment.

To resolve the issue, I had to set the path argument of the treikon function to a folder that contained 6 required dlls.

c = treikon('IDN',... 'C:\Program Files (x86)\Thomson Reuters\Eikon\X\Bin')

In my installation of Eikon, these 6 dlls were contained in 2 different folders. So I copied 2 of them into the folder that had 4 of them ie to C:\Program Files (x86)\Thomson Reuters\Eikon\X\Bin.

FYI, the required dlls are Interop.EikonDesktopDataAPI.dll, Interop.AdfinXAnalyticsFunctions.dll , Interop.AdfinXAnalyticsObjects.dll , Interop.Dex2.dll , Interop.RSearch.dll , Interop.RTX.dll

Are you calling it from 64 bit MATLAB? That pathname with the (x86) implies a 32 bit MS Windows executable, which you would not be able to call from a 64 bit version of MATLAB.
