I received this error when trying to install Oracle 10.2g on AIX 5.3. All Oracle requirements were met, so it didn't make sense. Turned out it missed the fonts on my [[cygwin]] installation.

Error:

This is how to check if the required fonts are installed:
<code>
C:\cygwin\bin>cygcheck -c -d | grep font
fontconfig              2.6.0-1
ghostscript-fonts-other 6.0-1
ghostscript-fonts-std   8.11-1
libfontconfig1          2.6.0-1
libfontenc1             1.0.4-2
</code>
As you can see, no fonts...

I changed my own howto on installing [[cygwin]], and after also installing the correct fonts it worked, and this is, how the previous command output looks like when the fonts are installed:
<code>
C:\cygwin\bin>cygcheck -c -d | grep font
font-bh-dpi75                  1.0.0-1
font-bh-lucidatypewriter-dpi75 1.0.0-1
