I must be completely stupid I guess

Because I can’t seem to select my hard drive to run this scan. I sure don’t want to scan individual apps one at a time. What a total waste of money. If anyone can help me set this up I would be grateful because frankly customer support was vague and when you select Help in the app, it says it can’t be found. I should have just flushed $40 down the toilet, it would have been more satisfying!
