ImageMagick works in 1.4.10; Not in 1.5.10

[caprifolia]

This is for two different galleries in different websites on the SAME Server

as the subject line states => Older installation has ImageMagick working just fine; newer one does not.  I get an error message uploading to the newer installation when using imagemagick.  Error= Error executing ImageMagick - Return value: 1

GD 2.x works fine in the new installation;  No problem uploading a new image to the older Coppermine installation.

The albums and include folder permissions have been set correctly as have the file permissions
the path to ImageMagick is the SAME in both installations.

So what the heck is going on?

Really, I read that!
I had set every folder to 777; I reset every folder to 755 and now it works.

Thank you.
