Fix error: These are not actually errors !

Many users can got one of this system messages:

  • There was a problem sending the command to the program.


  • Windows cannot find the file, Make sure you typed the name correctly, and then try again.
  • Cannot find the file (or one of its components). Make sure the path and filename are correct and that all required libraries are available.

These are not actually errors …
This problem occurs due to Dynamic Data Exchange (DDE) feature. DDE is a type of communication protocols which is used by Windows to open certain filetypes which require this protocol for communication between source and target programs.
DDE mechanism is used to prevent unnecessary opening of multiple instances of a program if one instance of that program is already running in background. So basically DDE helps Windows in saving computer resources so that you get better performance from your computer.
In my case the error message is shown only once and you’ll be able to open the file in second attempt or each time you try to open the file.

Create your GUID with Visual Studio Express 2013 .

The file called AssemblyInfo.cs contains information about your programme and provides properties for getting the information about the application, such as the version number, description, loaded assemblies.
This is just a simple example and you can read the docs from msdn docs

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("your tile")]
[assembly: AssemblyDescription("your descriptions")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("your product ")]
[assembly: AssemblyCopyright("Copyright ©  2015")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("......your-GUID.........")]

// Version information for an assembly consists of the following four values:
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
[assembly: AssemblyVersion("")]
[assembly: AssemblyFileVersion("")]

When you create the project you will find this file on Solution ExplorerProperties .
Into this file you need to add your GUID.
A Globally Unique Identifier is a unique reference number used as an identifier named GUID.
The GUID refers to various implementations of the universally unique identifier and usually stored as 128-bit values.
You can use the tools in Visual Studio Express 2013 on the Tools menu, click Create GUID. The Create GUID tool appears with a GUID in the Result box.
