Have you tried version 5.11.0.0? Did you run into the "Codec Missing" error? Let me know in the comments below.
Format Factory isn’t the fastest converter on the market, but its sheer format support and zero cost make it an essential tool for beginners and casual users. Version 5.11.0.0 fixes several annoyances from earlier 5.x builds, so it’s worth upgrading if you still run 4.x or an older 5.x. format factory 5.11.0.0 download
