body: <p>This is my first question. if happens any mistake please ignore. </p>
  
  <p>We develop an inventory system using C# in visual studio, database design by MS server management and create a setup file. To access database we use ODBC.</p>
  
  <p>The problem is started when we installing the setup file into another computer. After the installation clicks on the .exe file, the error will appear as shown in the image. </p>
  
  <p>Most of the time it may happen because doesn't set correctly connection string, can anyone please be of any assistance, </p>
