You can and at the same time you cannot. With LabVIEW, you can create the necessary files to create a help file, but you can't create the help file. In order to create your help file, you need a WinHelp compiler.
Also, what LabVIEW allows you to do is to create a file that correspond to the documentation of you VI, so you need to fully document you VIs first.
To document you VI, go to
File -> VI Properties and select "Documentation" from the menu. You can access the VI Properties also by Right-clicking the VI icon in the top-right corner of the Window. To document the controls and indicators in your VI, Right-click the control or indicator and select "Description and Tip...".
To create the documentation files, go to
File -> Print.
At some point, you will have the option to select a
Destination. Select "RTF File" to generate the files a WinHelp compiler understand.
As you will see too, you can also create html files for your VIs. It can be a good alternative for WinHelp files.
There are some nice Help editors outhere. I use
HelpScribble. You can see a very simple help file I created with HelpScribble in my small project
VI Background Check.
