MinimServer on QNAP TS-231 P

[tullio]

Thank you very much fpr your quick reply. Unfortunately, in my case the JRE was not installed automatically. Instead, I got the following error message when trying to install MinimServer:
"MinimServer 0.8.5.2 installation failed. The following QPKG must be installed and enabled: JRE >= 1.7 || JRE_ARM >= 1.7."
What can I do to avoid this error?

Thanks again.
