Getting an error message when trying to download Deluxe file. Error: Intuit Update Service V5 could not be stopped. What can I do to resolve?

I installed the Deluxe file, but got an error message that something went wrong and it wouldn't open. I uninstalled the Deluxe file and tried to reinstall but now it won't install. I'm using Microsoft 10 and haven't had trouble installing Turbo Tax in the past, but I've always had a disk. This year I don't have a disk. Bought it at Sam's Club. The message also says, "Verify that you have sufficient privileges to stop system services" I don't know why it's asking to stop anything, I'm trying to install. I'm at a loss. Any help is greatly appreciated.
