Just a quick note about the user profile, it is not set (by design) so
I won't try to access the profile data.

More on the impersonated problem later.

I checked using Process Monitor - convert.exe is NOT started by the
correct user:

User: NT AUTHORITY\NETWORK SERVICE
Auth ID: 00000000:000003e4

I'm not sure the users environment is set, that's a different thing.

But is it the correct user?

Hope I'm not too verbose. Maybe it helps to see that calling this

exec("d:/programme/imagemagick/convert.exe -density $density
$baseDirectory/$bookId/document.pdf -quality 95
$baseDirectory/$bookId/$version/page_%04d.jpg", $output);
print_r($output);

in a script run by the webserver (as above) causes this:

    [2] =>    --nostringval--   1   true
