I had the same problem, and opened a ticket as suggested. This was the response I received:
“Can you try to reinstall AdoptOpenJDK with Administrator privileges, using this link: https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u202-b08/OpenJDK8U-jdk_x64_windows_hotspot_8u202b08.msi ? Please let me know if the issue gets resolved. “
After that, I ran the installer again and had no issues. Hope this helps anyone else having the same problem
I had the same issue on a fresh installed Windows10 device. Running https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u202-b08/OpenJDK8U-jdk_x64_windows_hotspot_8u202b08.msi resolved it @Gerrit Kiefer thanks!
Sounds like a question for the Mendix support. Did you tried to create a ticket about?
