When you add a new instrument using the Keithley Configuration Panel (or NI Max) and want to use a logical name, it must be attached to the VISA resource as follows. Right click on the Logical Name folder and attach a resource: Also, can you communicate with your VISA resource using NI VISA Interactive control??
But you do have the Keithley Communicator.
To ensure that you can communicate with VISA, open the Keithley Instruments -> Keithley Communicator.
Then click on the Open Instrument button and enter or choose the VISA resource that matches your 2700 setup in your case I believe this is ASRL3::INSTR and then press the OK button.
Then enter *idn? in the lower portion of the window and press the Run button. If all goes well you should see the instrument respond... If this works, then the problem is with your program..I don't know much about your program, but be sure it is set for 32-bit or x86 target and not 64-bit x64 CPU. You might look - for some examples we have posted and try them out to see if you can get something to work:

Program that i run is an example program from directory: C:\Program Files\IVI Foundation\IVI/Drivers\KE2700\Examples
My opearting system is win7 64 bit. Is it a problem?
Then do a Build -> Rebuild Solution.
Then try the example again.
(If still having problems... which example folder and example are you trying to run? What version of Visual Studio do you have?)
Double check that you changed the build target to x86, and then rebuild the solution and try again.
Also, try the other examples in the .NET2 folder and see if they work..
