The requested file xxxxxxxx.otf was not a valid font file.

When attempting to open any OTF (OpenType Front) file in the C:\wINDOWS\Fonts folder, the user would get the following error:

The requested file xxxxxxxx.otf was not a valid font file.

The system was a Dell Latitude E6500, running Windows XP Service Pack 3, with a Core 2 Duo 2.66 Ghz, 4 GB RAM, and an NVIDIA Quadro NVS 160M video card.

Here’s the fix:
Open up regedit (Start -> Run -> regedit)
Navigate to: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/SessionManager/MemoryManagement
Add a new DWORD named SessionImageSize and set to decimal value 20
Reboot

    Wow. I wasn’t sure if this would work, but I’m very happy to say that IT DOES WORK! Now I can access all of my fonts from InDesign and Illustrator too.

    Thank you very much!
