Disc Won’t Open Because Windows 7 is Using Large Font Mode

Recently, I purchased a book which comes with a DVD for my foreign language class. It is said on the label that the disc is compatible with Windows 7. Fortunately, I haven’t upgraded yet to Windows 8 though I already ordered one online.

When I got home, I skimmed through the first chapter of the book and immediately ran the disc on my machine to take the test. Unexpectedly, it won’t open. An error message keeps on popping-up.

“We have detected that Windows is using large font mode. We require that you set up Windows to use normal font mode”

This is the first time I encountered such error for 5 years of using Windows. I have installed a lot of DVD software in the past and I never had a problem.

I tried to figure out what’s causing the error on my own and finally solved it after 30 minutes of trial and error. If you are having the same problem, the first thing you can do is to change the screen resolution of your monitor. Here are the steps on how to do it:

1. Right-click an empty space on your desktop.

2. Select Screen Resolution

3. Change the current screen resolution of your monitor by clicking the Resolution drop down options. Select a non-widescreen resolution by moving the slider.

Here’s a list of non-widescreen resolution for your reference (just pick one):

640×480
800×600
1024×768
1152×864
1280×960
1400×1050
1600×1200
2048×1536
3200×2400
4000×3000
6400×4800

4. Click Apply – Keep Changes.

5. Re-run the disc.If the steps above do not solve the problem, you can try adjusting the Windows font size by going to this path: Start – Control Panel – Appearance and Personalization – Display. OR, right click an empty space on your desktop then select Personalize – Display. Adjust the font size to default (Smaller) or Medium then click Apply. After that, re-insert the disc on your machine.

If the problem is solved by changing the display resolution, don’t forget to change it back to the original setting. You just need to adjust it temporarily for the sake of loading the program without error.
