Error code 1500

Downloaded digital copy from Costco.ca.  Ran the setup file.  Won't install. Gives me Error Code 1500; says I have to finish installing that other program first.  No other programs are being installed.  Just TubroTax 2018.  This happened last year with 2017 as well.. the digital download from Costco didn't take.  I had to download direct from Intuit and then use the purchased Activation Code to make the program work.
