Hallo SylvaniLS,

first of all thank you answer.  I use Windows 10 Home 64 bit version with the latest updates, also Java 8 with the update 221 Realease from 16 July and the OpenGL 4.6 is up to date. Graphics cards is Geforce GTX 1060. Direct version 11.3.  I downloaded the zip file then opened it then clicked blueprint.bat.  Then this error message comes.  I would be grateful for Hielfe.  Greetings Ches

Grüße Ches

Hi there, you're opening the blueprint.bat file from inside the zip? You should first unpack the zip on a folder, then run it from there.

Did you simply opened the zip archive or did you extract it somewhere in your computer?
The correct way is to extract it and only then launch the batch file.

EDIT: oops, anticipated.

I've just stumbled across this (OK, a few years too late) and tried to get it running without success. I suspect it's either a Java version issue or my graphics card is ancient but it's hard to tell without the source code. I'm an enterprise Java architect by trade and would love to see the code to this as I've never done anything desktop or graphics related. It looks amazing. If you ever want a small group to help you out, let me know, I might have skills.

Here's the command line output and stacktrace

PS I noticed experiments with iText for PDF building. I know this project is dead but read the iText licence options very very carefully...
