Update: I tried Inkscape 0.47 instead of 0.48 now, and here an error message is briefly displayed in the console window (translated):

Error: Main class C:\Users\USER\AppData\Local\Temp\ink_ext_XXXXXX.svgMEMVCW couldn't be found or loaded

Does that ring a bell with anyone?

Best regards,

Gerrit

> The program wouldn't return any document, but the error message would be displayed by Inkscape. However, when I test this, nothing gets displayed. When I change the program to write a file, that file doesn't appear either, so I guess the program isn't called. I can change the command text to any other value, but there is no notification that a script couldn't be found.
