I recently tried Spark 2.7.0 Beta 1 (_online build), and it refuses to install because I "don't have a JVM". Of course I do have a JVM, I have Java 7 installed. However, it refuses to recognize this. I got it to install by installing Java 1.6, but I cannot make it use Java 7, even after removing 1.6.
The installer gives this error:
Spark gives this error:
Considering this statement:
About Java 7: Spark 2.7.0 will run with Java 7. Please interchange the bundled JRE (located at Spark-install-folder\JRE) against a Java 7 JRE or use the installer named spark_2_6_3_12555_online.exe and install Java 7 as default on Windows. Using Java 7 will stop Spark from stealing the focus, when a new message is received.
It seems I must be doing something wrong, but what is it?
