Gsdll32.dll please check ghost script program

Dear dfp forge

 

One of our costumers has the following problem.

When making a pdf in word or excel it does the job.
But when he selects a file from windows explorer, pdfforge gives the error "gsdll32.dll  please check ghost script program".

 

What can we do to solve this problem?

Tnkx in advance,
Diabolo ICT
