[Scribus] Can't edit images

[François Pallut]

Hi,
I use Windows XP sp2 (athlon 3 Ghz, 1 Go) and Scribus 1.3.4.

But, with my "normal" machine, Scribus can't edit images.
When I'm trying to edit an image, a message appears : The program 
C:\Program Files.....gimp-2.2.exe is missing.
But Gimp is in the box.

In a VMWare, i have no problem in editing images.
With an other machine, the same installation works perfectly.

So, have you a solution ? What's wrong in my machine ?

Thank's
Best regards
