Bump. This exception happened to us after a user reported this issue after installing a system update for Windows.

[DevCharly]

Unfortunately can not reproduce this exception...

Seems that extracting the DLL from flatlaf.jar to temporary folder works fine.
Also loading the DLL seems go well.
But invoking a method in the DLL fails...

Could you please run following on command line and post the output:

dir %TEMP%\flatlaf.temp
java -XshowSettings:properties -version

[DevCharly]

Does this occur on every start? Or occasionally?

[ThisOtterBeGood]

I'm sorry I hadn't have time to test last week. I just realize it might be a problem with our corporate execution policy, so you might want to stop investigating until i can hash that out.

@ThisOtterBeGood thanks for the info. This could be the reason.

I've modified the code to catch the UnsatisfiedLinkError and continue with standard window decorations.

A updated demo is in the build artifacts here (at the bottom):
https://github.com/JFormDesigner/FlatLaf/actions/runs/1547109693

@Nibby please try the latest 1.6.5-SNAPSHOT: https://github.com/JFormDesigner/FlatLaf#snapshots

[ThisOtterBeGood]

It's our execution policy. It prohibits the usage of ('%temp%\flatlaf.temp\flatlaf-windows-x86_64-9110333436000.dll"

That snapshot works: https://github.com/JFormDesigner/FlatLaf/actions/runs/1547109693

Thank you so much!

[DevCharly]

@ThisOtterBeGood many thanks for the update.

FlatLaf 1.6.5 released
