imagemagick return error = 127?

[shellie]

i've seen return error =1 but the one i'm getting is this:

**
Error executing ImageMagick - Return value: 127

Cmd line :
/usr/bin/convert -quality 80 -antialias -geometry 100x56 'albums/vicki/1.jpg' 'albums/vicki/thumb_1.jpg'


The convert program said:
sh: /usr/bin/convert: No such file or directory
**

the server i'm on is linux. can someone suggest what i can do? i've tried the troubleshooting tips in config and it didn't work.

all the folders are chmod to 777. i've tried 755 too and that made it worse.

thank you!
