FW: Okular cannot display PDF files

[Lillig Joachim]

Hello,

I installed KDE for Windows 4.3.3 on Windows XP SP 3
Everything but the games and torrent and irc clients.

Okluar can't display PDF files; the error message is:
Could not open file <file name>.
(Okular can open images - PNG, JPEG, ...)

First I had the Visual C version, then MINGW4, then Visual C again.
After the scond Visual C installation (every installation into a fresh
directory) I could open a PDF file once.

What can I do? How can I get better error messages?
