Hi,

 

Select File>>Open Samples.  Open any circuit that was loaded with Multisim, simulate the circuit and see if you got the simulation error message "No such file or directory".  If yes, have a look at this knowledge base:

If you didn't get an error when simulating our sample circuit, select File>>About Multisim, tell me which version you have installed.
