I did not find Czech.ini file in that PDFCreator v.1.2.0 although this language is announced in update site.
So, I have had write it myself. I would like send it to authors of this program, but no e-mail address is available.
If anybody wants this Czech.ini file, send me a message to: email@example.com.
It is free, of course.
I am sorry for my horrible english.
