Sorry. I think yesterday I sent you this message, but to the wrong address. That's why I'm repeating it today. I keep trying to make code to run my program code from Windows. My task is that when I click on the address of my file from Windows (in Windows Explorer), then Excel should open my user form with one click. From it I will run my program. I have tried your suggestions but have not been successful. Because of my main problem - I'm a beginner. In this situation, is it possible for you to send me a fragment of the program, where the code recommended by you would already be used. Excuse me please.
