Matlab2015b Error in actxserver (line 86) h=feval(['COM.' convertedProgID], 'server', machinename, interface); The specified procedure could not be found

I'm trying to connect matlab to TWS through API - ib=ibtws('',7496) -. OS is Windows10 x64 .First I had the 2016a x64 version and downgraded to 2015b 32bit. The same with TWS, had to downgrade to 957.3 release and x86 version. Already installed C++ redistributable 2005, 2008 and 2010 in x86 version. Already installed 970 API from IB. And I keep getting the same message:

>> ib=ibtws('',7496); Error using feval Server Creation Failed: No se encontró el proceso especificado.

Error in actxserver (line 86) h=feval(['COM.' convertedProgID], 'server', machinename, interface);

Error in ibtws

I've Been trying to solve this all day and nothing seems to work. If anyone has found a solution, you can spare me a stroke.

Thnx!!

Rejoice! Found the solution .

This is for 9.71 version of API. It seems that Matlab trading toolbox is not updated to the newest version of API

Here's the sequence

1. Uninstall the API component by navigating to Control Panel -> Program and Features

2. Locate and delete the following files if they are still present:

C:\Windows\System32(SysWOW64)\TwsSocketClient.dll C:\Windows\System32(SysWOW64)\MsFlxgrd.ocx C:\Windows\ddedll.dll

3. Restart your computer.

4. Install the Microsoft Visual C++ 2005 SP1 Redistributable Package (x86) http://www.microsoft.com/en-us/download/details.aspx?id=5638

5. Install the Microsoft Visual J# 2.0 Redistributable Package. http://www.microsoft.com/en-us/download/details.aspx?id=4712

If the problem still persists, you may have to register the Tws.ocx file manually. It is essential that you run CMD or command in Administrator, even though you login as local administrator. Please follow the below steps:

1. Copy Tws.ocx (C:\TWS API\bin\ActiveX\ to the following directory: C:\Windows\System32(SysWOW64)\

2. Click the Search Windows icon (Magnifier glass) and in the Search area, type "cmd”

3. Right click the "Command Prompt" banner, and select "Run as Administrator"

4. At the command prompt, enter: %systemroot%\System32(SysWOW64)\regsvr32.exe Tws.ocx

5. This should successfully register your Tws.ocx.

It doesn't work... I have still this message :

>> ib = ibtws('',7496) Error using feval Server Creation Failed: Le fichier spécifié est introuvable.

Error in actxserver (line 86) h=feval(['COM.' convertedProgID], 'server', machinename,interface);

Error in ibtws (line 38)

I realised all the steps describe here above but nothing changes...

Does anyone have an idea ?
