Execute desktop application on client machine.

Question

I am new to develop a .NET application.

Created the desktop application and publish it on 32 bit win 7.

(using sql server 2008 r2 and visual studio 2010).

When I install and execute desktop application on client machine which is win 7 64 bit,

its giving the following error.

 

 

 

 

 

I tried to downgrade sql server version and also tried for latest version of sql server (upgrade).

Still giving the same error.

Please help anyone has the solution.
