The following steps will reproduce this issue:
1. Open K2 Management and navigate to Integration > SmartBox Security
2. Add the following users: K2 Service Account, K2 Admin Account, K2 SmartForms account
3. On K2 Five, upgrade to any Fix Pack.
The error appears when installing the fixpack on K2 Five:
"Component.ExecuteTarget: Logged Error: Target did not complete successfully: K2 for SharePoint 2013.kspx"
This issue is caused by the SmartBox Security rights (Create, Update and Delete) given to accounts.
If you remove these rights, then the install passes successfully.
