Hi @Perfect_Human_Interface, I had another user report issues with updating the plugin. They were getting the error:
Error Code: IS-EO-Lnc-BldInfo:Http-403
Did you get the same error code when you tried updating?
When searching for this error, there I found a recent discussion: Error Code IS-EO-Lnc-BldInfo:Http-403
Some users have reported that simply closing the Launcher through the task manager and then running it again in administrator mode allowed them to update.
