STM32CubeProgrammer not working, starting up and then closing immediately

[JGale]

I've been using the programmer for a couple of week now and everything seemed to work fine.

When I powered up my pc and tried to run the program I got a starting screen that quickly disappeared. This happened even after I reinstalled the program, anyone has had this problem and knows how to solve it?

Hi,

If someone still have issues with running STM32Programmer, seeing splash screen and then nothing more:

After going through ALL the answers I could find on the internet, I finally was able to fix:

1. make sure the JAVA (JRE) is from ORACLE!
2. JAVA_HOME points to the JRE directory
3. add JRE to PATH

Hi,

Does it mean that STM32CubeProgrammer is not support OpenJDK/JRE in Windows platform?

I am trying to use OpenJDK/JRE in Win10 for STM32CubeProgrammer installation and with no luck.

I am also having this problem, yes, I have Java 9 installed I NEED to have it installed. Why is this still an issue, I thought the ST team was fixing it some time ago.

Indeed this fine piece of software does work only with Oracle's Java which is not free to update! I wasted many hours trying with Amazon Corretto and AdaptOpenJDK - it starts and immediately disappears after the splash screen. I don't know why it uses Java at all as it also seems to use Qt libraries!

BTW, this is the second ST software I install after STM32CubeIDE, which also still has well known bugs and newer MCU firmware downloads fail - they have not been fixed since years. Very frustrating!

Issue is fixed by adding -Djna.nosys=true in the newline in C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32CubeProgrammer.l4j.ini

This worked for me.

Ok I am having the same problem. my programmer just arrived and I am trying to Install STm32cube on my 64 bit win 7 pc. I downloaded the correct package and i see the splash screen and a spinning circl for a couple seconds and then poof gone.

 I ahve read through this thread and I tried editing the STM32CubeProgrammer.l4j.ini by adding a line
-Djna.nosys=true

and i get the same results. splash screen for a second then gone.

I do have other ST programs on this machine.

I seem to have Java on my machine as i have the arduino IDE on here. Not sure how to find the Java_home or JRE directorys??
