I have installed jdk11 and added it to PATH and set the JAVA HOME variables, still don't know what to do

Are you sure that's a windows jar file?

[WrenVin]

Yes we are using the windows64 jar file

[WrenVin]

My team never found a solution, we ended up switching to Linux and the install worked fine there

Weird, this lives in a try-catch block https://github.com/PhotonVision/photonvision/blob/master/photon-server/src/main/java/org/photonvision/Main.java#L299, this means that it failed to load the native libraries btw.

Just confirmed 2023.2.1 works in Windows 10 with openjdk 11.0.7

[WrenVin]

The only difference with mine was using Windows 11

I run windows 11 and works for me. Curious what the difference is that's causing the failed load

[zholly15]

We are also running into this issue on a Windows 11 Machine. Java 11 is installed and we are targeting the 2023.3.0 Jar.

@WrenVin @zholly15 Is this problem still relevant? Try the latest dev build, some changes were made in upstream wpilib gradle tools that improved how opencv is loading
