Hello, I am new to this forum, but have been a Tivo user for over 15 years. Have gone through a few Tivo's due to hard drive crashes/corruptions. I was instructed by Tivo I could save my programs I recorded by using this program. I have many programs on my PC's hard drive as well as having 3 My Passports Ultra drives loaded with programs. I had not used my Tivo desktop in a good 2-3 years until this week. I believe I was using Windows 7 or 8 at the time. When I clicked on my desktop icon now, it simply will not open. Here is the exact message I got: "Unable to begin Tivo Desktop. The parameter is incorrect" I'm assuming this is solely due to Windows being upgraded to now Windows 10 from whatever I had when it was working 2-3 years ago ago, Windows 7 or 8. Can anyone offer me step by step guidance on what to do? Thanks in advance.
