I have created a music notation score and in the online "help" from Finale, they suggest if you want to save a file as .pdf you have to purchase Acrobat.
When I tried to follow the directions below I cannot find the "postscrip" (*.ps) file that I "Print to File" with. Here is what Finale instructs. I am using WIndows 7 if that helps. (I've tried naming the document a unique name and doing a "search" but it will not locate anything.
There’s more than one way to create a PDF, but this method will give you more control over the results. See your Adobe Acrobat manual for full details.
