# JAG3D - problem with starting application

Hello Micha, JAG3D wont start. I used the older version of the JAG3D program more than a year ago. Now I tried again to use your latest version from github, but the program wont start. I installed Java 10.0.1 version. When I click on the jag3d program icon, only splash appears and then it disappears. The program never starts:

Can you help me with this problem?
Best regards,

## JAG3D - problem with starting application

Hello Alija,

JAG3D wont start. I used the older version of the JAG3D program more than a year ago. Now I tried again to use your latest version from github, but the program wont start. I installed Java 10.0.1 version. When I click on the jag3d program icon, only splash appears and then it disappears. The program never starts

Can you provide some further information? Please open a windows shell (CMD) and check the installed java version, i.e.

java -version

on my operating system, the output is

If yes, please try to start the application via command line, i.e.

java -jar jag3d.jar

Please note, you have to switch the path to the executable jar file, see Screenshot

Does the application start? If no, do you get some error or exceptions on the cmd?

regards
Micha

## JAG3D - problem with starting application

Hi Alija,

after your instruction, I'm getting this message from cmd.

Fine. I was able to reproduce your error and I will release a robuster version during the next days. The problem is the so-called history file (which stores the last opened projects). Your history file is corrupt because the entries contain invalid path characters. The error message is:

java.nio.file.InvalidPathException: Illegal char <?> at index 41: C:\Users\alija\Desktop\...

Currently, the InvalidPathException is not catched by JAG3D but I will fix the problem.

To start your current version of JAG3D, please delete the history file (or correct the content in your history file). The history file is located at:

C:\Users\alija\.jag3d_history

It is a simple ASCII file that contains the file path of the last opened projects (one project per line). I believe, at least one project contains the problematic ?-character which causes the InvalidPathException.

regards
Micha
