Multiple pdfcreator

Hi,

 

I am calling command line pdfcreator.exe via a vb program to print PDF files.

However i have few instances of the same program calling pdfcreator.exe. Will this causes any errors? Does calling the same pdfcreator.exe without any options actually calls just the same instance of the printer?

Cause i am hitting a C++ runtime error once in a while and not sure is it cause by this

 

hope someone can advice me on this

 

thank you
