A java Runtime Environment (JRE) or JDK must be available in order to run Knime

Updated from previous version to KNIME 5.2 from notification given by KNIME software. When trying to start KNIME after version update I get error message:

A Java Runtime Environment (JRE) or Java Development Kit (JDK)

must be available in order to run Knime. No Java virtual machine

was found after searching the following locations:

javaw.exe in your current PATH.

I understand Java should install bundled with KNIME package and have faced now issues with earlier KNIME versions. What should I do now, please?
