While trying to convert wmv to animated gif using ffmpeg in Windows 7, I ran into an issue. 

Microsoft Windows [Version 6.1.7600]

C:\>ffmpeg -i test.wmv test.gif

test.wmv: could not find codec parameters

What does this mean and how can I solve it?

The message seems like a parsing error. Your FFmpeg version however is several months old. The project is continually evolving. and with possible bugs like this, always try and use the latest version of FFmpeg.

Chances are bugs have already been fixed in the current Git head or the latest release.
