I followed all the steps normally.
at the end when I launch Sage 50. a window opens and displays: Bad Key file
then this puts me this product not properly install
- I resumed the process several
- I have to deactivate my anti-virus
- I disable all firewalls
- restart my computer
- use the StudentVersCleanUp
it always puts me missing one of the files
What should I do and I have course and exercises to do
