Although my keep steep drop in amount of K2 posts from my side with more than high probability in the future, I’m keep jotting little things for now. The other day I was a bit perplexed by K2 Platform Classic setup manager which blocked me from adjusting K2 service account like that:

What it actually does is forcing you to use currently logged in user. And addressing why part it happens when you have developer license – in that case setup manager forces you to use currently logged in user as a “service” account (remember that Developer license requires you to run your K2 service in a window within interactive user session). Just though it may be useful to write this down and share.
