I want to access the NGM CD set

[Dale]

Does anyone know how to access/read the NGM CD set? Is there an update I am not aware of? I cannot now use the app on my Windows 10 PC. Below is my question to Chat-GPT on how I might do this, but its response is a more complicated than I am now comfortable with (old retired engineer). Yes, I know I can buy scanned versions of the magazines on ebay, but they are quite expensive and do not offer the really valuable database/search flexibiity of the CD app. 

Would very much appreciate any guidance here.

My Question to Chat-GPT

I have a CD collection of scanned National Geographic Magazines that uses an app one must load on one's PC to be able to access them. This app is more than 20 years old, written for a much earlier veraion of Windows. It will not run now on my Windows 10 PC. Is there any way I can get it to run?

Chat-GPT's response:

Short answer: yes—but not directly. What you’re encountering is a very well-known compatibility break with those National Geographic CD/DVD collections.

Let me be precise about what’s going on and your viable options.

Why it won’t run on Windows 10

Those National Geographic discs were typically built for Windows 3.1 / 95 / 98, often using:

• 16-bit installers

• obsolete frameworks (e.g. early QuickTime, Adobe Director)

Modern Windows (64-bit, including Windows 10/11) cannot run 16-bit applications at all, regardless of compatibility mode. (Internet Archive)

Even where the data is fine, the viewer application is the problem.

Your practical options (ranked)

1. Best solution: Run a virtual machine (VM)

This is the most reliable and professional approach.

You install an old Windows inside your current PC, then run the CD inside that.

Typical setup:

• Install VirtualBox or VMware Workstation Player

• Install Windows 98 or Windows XP inside it

• Mount your CD (or ISO image)

• Install/run the National Geographic software there

✔ Works almost always
✔ Preserves full functionality
✔ Handles 16-bit + legacy dependencies

This is explicitly noted as necessary for these discs—“works in a virtual machine” but not on modern Windows. (Internet Archive)

2. Try Compatibility Mode (low probability)

Right-click the installer → Properties → Compatibility → set to:

• Windows XP (SP3)

• Run as Administrator

This sometimes works for later versions of the collection, but:

• Often fails due to 16-bit installer limitations (Microsoft Learn)

---

3. Extract the data and bypass the app

This is more “engineering-minded” (you may appreciate this approach).

Steps:

• Copy the CD contents to your hard drive

• Look for:

  • PDFs

  • JPGs

  • HTML files

  • video files (e.g. .MOV, .DAT)

Some discs are simply containers with a custom viewer.

You may be able to:

• Open directly in a browser

• Use a media player like VLC media player for embedded content (Microsoft Learn)

✔ No legacy OS needed
✖ Often loses indexing/search functionality

---

4. Use DOSBox (only if DOS-based)

If the software is DOS-based (less common for Nat Geo discs):

• Use DOSBox

This works well for DOS programs, but most Nat Geo discs are Windows GUI apps, so VM is better. (Wikipedia)

---

5. Odd workarounds (situational)

These sometimes help but are unreliable:

• Change system date (some installers fail due to date checks) (ngscollectors.ning.com)

• Use virtual drive software (for copy protection quirks) like DAEMON Tools (Wikipedia)

---

My recommendation (given your background)

Given your engineering mindset and desire for a robust solution:

👉 Go straight to a virtual machine with Windows XP

It’s:

• deterministic

• fully compatible

• once set up, reusable for all legacy software

---

If you want, I can help you set it up

I can give you a precise, step-by-step configuration:

• exact VM settings (RAM, video, CD mounting)

• where to obtain a legal XP image

• how to optimise performance and file sharing

Or, if you prefer a lighter approach, I can try to reverse-engineer the CD structure with you to bypass the viewer entirely.

Dale,

This Discussion might help.

You need to disconnect from your internet, manually re-set your PC's clock date to something pre-2015 or 2014, and reinstall your program + DVD-rom's. 

* (should also work in same manner for the earlier "CD-rom" sets, but set your PC date clock to something pre-2009) *

After you've installed and closed and re-opened, you should then be able to reconnect your internet and re-sync real-time.
