Ok, I tested it right now and like expected without any problem...

My steps:
1. T-3-1-2-1 (don't know why, this is a first time happens, but 3 applets, not uninstalled successfully. I removed them from Apps Manager)
2. reboot
3. T-3-1-1-0 (system-ui installed without problem) -> pressed R
4. pressed 1-1 (all applets installed successfully)
5. Checked status menu -> static menu OK
6. T-3-2-2 (status bar refreshed)
7. Checked status menu -> dynamic menu OK

No problem...
