We have a user when is running Vista64. They have installed the OEC API COM client. In our code at this point:

Quote: HRESULT res = m_API.CreateInstance(__uuidof(OECAPICOM::OECClient));
if (!m_API)
{
g_p_MessageLog->AddMessage("Failed to create OEC API COM instance.", SW_SHOW);
return false;
}


We are getting an error. m_API is null. We have not seen this before, unless the COM Client is not installed. On this system we installed the correct version 3 times.

We also use another COM component and we are not seeing a problem with that one on this users Vista64 system.

It might be related to the 64bit OS - while .NET is working in 64bit mode, COM and native applications are still in 32bit - so they could not interoperate.

We will research this issue.

Please download and install the updated OEC COM API - registration of the component was fixed to work in 64 bit systems.
