Can`t find it

Can you tell exactly where to look? Which folder?

Hello Fredo6!

Big Thank`s for your work and this amazing plugin

I have made made a mistake when setting up a plugin to generate video...I choose incorrect files when program asking me for "How to get FFMpeg"
(ScreenShot001)

after my mistake I have this:
(ScreenShot002) Looks correct, but it is not working. Error in the end of Generating

Now I understand how to make correct, I download right plugins (from here: http://ffmpeg.org/download.html)

BUT: I don`t know how to clear old incorrect plugins for Generate Video. How I can turn to situation in ScreenShot001?

(Deleting folders Fredo6 in plugins - didn`t work)

Really need Your Help!
