Tom suggested I copy this from my posting in Buy/Sell/Trade.

I wouldn't bother with the CD or DVD ROMs for NGM. The picture quality is abysmal, and isn't that the whole reason for Geographics? On the web at Internet Archive you can find old NGs with great picture quality.

Error Message During Install

I discovered this yesterday [May 2024] 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!
