Error Message During Install

I discovered this yesterday when I was trying to install the software reader on a new computer.

What a crazy trick: change the date to 2010! (I was running the new computer under Windows 7)

I realize this is almost 4 years later but I have looked for a solution to the exact same problem with installing The Complete National Geographic on a Windows 10 and didn't find an answer. After much trial and error I discovered if I changed my clock back to 2010 it would install. Once the installation completed I could change the clock back to today's date and the software works.

I also came across this page while trying to install The Complete National Geographic on my HP Laptop running on Windows 10 as of August 2020. I had installed Adobe Air as the National Geographic support suggested (https://help.nationalgeographic.com/s/article/complete-national-geo...). Reading here, I thought I'd set the year to 2009 just to be safe (earlier than 2010) but it didn't work! Oy! So I tried setting it to 2010 and it worked! No installer error, now I can look at old Nat Geogs until school is back in session in a few weeks haha. thank you @ceezee1!
