good morning, I open this post precisely to determine which is the recommended Java version to install on the system and have a good performance of designer ignition. I have installed version 8 .381 and I have had a lot of problems, so I have decided to downgrade to version 8 .361. Do you know why this bad performance is due to the last version? regards ---

The version of Java you installed is irrelevant, Ignition 8.x versions ship with their own Java runtime. ---

perfect, thanks! so the recommended is 8++, even so I don't understand why the igniton/designer performance started to work better once I downgraded the version. ---

The minimum required version is Java 11 for most of 8.1.x, and Java 17 as of 8.1.33. The changes you made to the system Java had no effect. ---

No, the "oracle java version of the computer" is irrelevant. Vision Client Launchers also ship with their own Java runtime. ---

Can I use a free version of java? Or do I need to purchase a paid license to use Ignition? ---
