Hi, thanks
Okay there seems to be some weird problem trying to get one of the icons when opening a FileChooser in order for you to select the license file

So a few questions:
- Is there something non-standard about your Windows system?
- Does File:Open Folder work okay?
It may be this java bug - https://bugs.java.com/bugdatabase/view_bug?bug_id=8320692
If the issue is only with the Update License dialog you can get round issue as follows:
- Close Jaikoz
- Manually copy license.jai file to C:\Users\username\Jaikoz (where username is your Windows username) replacing the existing file
- Start Jaikoz
Well yes the File open folder worked fine. The program ran fine. It was just the Update License dialog that I had issues with. Went and moved license like you recommended and everything works fine. Guess I need to do some Java debugging to fully remedy situation. Thanks for pointing me in the right direction.
Great, I’m going to assume its the bug I linked to which means it can be fixed by bundling Jaikoz with version 23 of Java instead of the current version 21.
