[Typo3] ImageMagick 6.1.9 and read pdf

[Albert Dekker]

Hello list,
It will not be the first time: Image Magick and pdf.

I have one installation on local computer which works perfectly for 
image conversions. All tests in the install tool are oke.

I made a new install on our company server. Same IM version. All file 
formats are read except .pdf and .ai

I have the feeling that it is because of the path:
The company server (Windows 2000 server) is installed with XAMPP from 
Apachefriends. ImageMagick is installed in c:\apachefriends\xampp\IM619
It shows as \\Server02\apachefriends\xampp\IM619 in Explorer.
In the install tool I have tried give the location for IM as 
c:\apachefriends\xampp\IM619\ , both with forward and backward slashes 
and with and without the c:.
All options perfectly show the availability of Image Magick 6.1.9 at the 
given path. and that the available commands are convert, composite and 
identify.
When I check the "Read Image Formats" the pdf and ai formats do not show up.
The funny (;< thing is that in the local installation (i.e. on my 
laptop) it works perfectly the pdf command string gives the convert 
command as follows: Dump:
E:\apachefriends\xampp\IM619\convert -geometry 170x241! -colorspace RGB 
-quality 70 -sharpen 1x2 
E:/apachefriends/xampp/htdocs/xxxxxxx/typo3/sysext/install/imgs/pdf_from_imagemagick.pdf[0] 
E:/apachefriends/xampp/htdocs/xxxxxxx/typo3temp/pics/install_read_pdf.jpg

The new installation shows the pdf command string with the identify 
command and then fails.Dump:
c:/apachefriends/xampp/IM619/identify 
C:/apachefriends/xampp/htdocs/xxxxxxx/typo3/sysext/install/imgs/pdf_from_imagemagick.pdf[0]

Could someone shed some light on this,
