Where is the help file? VacTran does not seem to find it!
The help functions may have been installed in an unexpected location on your computer. This sometimes happens on non-US Windows installations.
There are two help files. One provides interactive help from within VacTran, the other is a PDF formatted manual with the same information. The interactive help file is named VacTran3.chm. The PDF file is named VacTran 3 Manual.pdf. The default installation location for the help files is c:/Program Files/Common Files/PEC
Two ways to find the help files:
1) If you search for these files using the Windows Search function and find them in another location, you can reset the location in VacTran using "Help|Set interactive help file..." and "Help|Set PDF help manual..." The interactive help will then be available throughout the program.
2) Download them to any folder on your computer, and the reset the the location in VacTran using "Help|Set interactive help file..." and "Help|Set PDF help manual..."
