I really liked VSM and the course did say you had to run the Viplan software if you wanted to use it in the exam but like the others I never loaded it, I just read the Viplan manual, plus i went on a VSM workshop which it turned out covered the Viplan bit enough to make it easy to understand.
If you find you want to use VSM then suggest you read the Viplan manual and perhaps buy Patrick's book (can't remember the title but I'll find it) that should cover it, but if you aren't going to use VSM then Viplan software is not necessary to complete the course.
