Hey my instance was working, then last month i upgraded it. After solving a bunch of problems with that, apparently "jira service desk" is no longer installed?

Lets start with what log is the message referring to? i have looked in both log file locations i know about (C:\Program Files\Atlassian\Application Data\JIRA\log) and (C:\Program Files\Atlassian\JIRA\logs) and neither has any logs updated around the time i am performing the install.
Not sure what else to try really. i looked at some forums posts and except one about installing licenses before upgrading (which i did do around the same time, cant remember order of operations) i cant see any commonality.
EDIT: turned on debugging for upgrade under logging and profiling and i get this. cant upgrade because its the same version. but the error does not go away.
