I seem to be on here more than you tube at the moment!
We have two little issues with our spark client.
if I click on the advanced button, spark crashes - XP64 SP2, AMD64, JRE1.6
on some clients, spark simply does not start. nothing is written to any of the log files. Spark 2.5.8 with JRE was sent via GPO. Anyway of finding out why this happens?
