VASSAL Dropdown Help menu- PDF files not opening

I’m not sure I entirely get what you did or see. Did you,

  1. Edit the Wing Leader module in the Vassal editor
  2. Saved your modifications to the module
  3. Open the module in the Vassal player
    • Clicked the newly added help entry with a PDF file attached
    • Clicked the newly added help entry without a PDF file attached
      What happened in either of these cases?

Perhaps you could take another module, say Anzio Beachhead (by yours truly), which does contain a PDF file, and then try to open that through the Vassal player (HelpShow rules for the Anzio Beachhead), and then see if you see the PDF file open up.

  • If the PDF file is shown, then the problem is certainly not with Vassal.
  • If the PDF file is not shown, then please report any error message and the content of errorLog (see How to report problems).

Did you check all running browser (Edge, Chrome, Firefox, …) instances to see if a new tab was opened up? Vassal may not necessarily focus the browser nor raise it to the foreground.

I guess the temporary folder is

C:\Users\paulr\AppData\Local\Temp

Assuming that is correct, and the created sub-directory is something like

vassal_12345678\123456789\VASSAL\help\Wing_Leader_VASSAL_Module_Notes\

with the file module-notes.html in it.

If so, then

  • press Win+R (Windows key on the keyboard held down and then press R).
  • In the dialog box that pops up, type
     cmd
    
    This will open up a terminal window (typically a black background with gray text in it), which displays a command prompt a la
    C:\> 
    
  • In that command prompt, type
    C:\> start C:\Users\paulr\AppData\Local\Temp\vassal_12345678\123456789\VASSAL\help\Wing_Leader_VASSAL_Module_Notes\module-notes.html
    
    and watch what happens.
    • What should happen, is that a browser window or tab will open up showing the file module-notes.html. If that is the case, then something truly odd is going on, and we’d need to do a much deeper dive.
    • What can happen, is that no window or tab is opened and there will be some error message reported in the terminal window. If this happens, then double-check that you have typed the correct path to the module-notes.html file above. If the path is correct, then the error message should give some indication as to what is going on.

Yours,
