SAP.Middleware.Connector.RfcDestinationManager threw an exception

[Former Member]

I have developed an application using VB in Visual Studio 2010 and NCO ver 3.0.0.42 and it works great on my development machine. I have deployed this application onto approx 100 machines including Citrix based zero clients , laptops and desktops and virtually all of them work no problem.

All the machines are running XP (32bit) and are built from a standard image .

However there are approx 12 machines hat give the above error with the following details :

I managed to find the issue using a tool called dependency walker .

The sapnco_utils.dll has a dependency on the Visual C 2005 runtime files and they were no on the machines that didnt work.

I installed the Visual C++ 2005 Redistributable SP1 package and it now works .
