If you did an upgrade, all your programs will still be on the HD.
I know where Johnathan is headed and he will solve your problem.
I, however, feel that you have another problem. If you upgraded, you are going to have many problems in the future, the upgrade is known for that. My advice,is take your DVD (even if an upgrade DVD) and make a clean install. The programs will be gone and so will future problems. If you have an old car and give it a great paint job, does it run any better? Just my opinion, which I submit for your consideration.
If you decide to take my suggestion, just repost and I will help you in every way. In addition, you can, also, go to you tube and watch the procedure, like I did.
Good Luck. We are all behind you regardless of your decision.
