I also have quicken 2000. It will run on, up to a win10 computer. It won't run on win11. I've tried quicken2011 and I don't like it at all. 
I have records back to 1992 on my quicken program that I can access at the stroke of a key that I don't want to give that up. Also have several entities stored on it and since I'm retired I don't need a newer program.
I'm going to dedicate one of my win 7 computers to the quicken program only and ride that till my end.
You might want to think about that.
