Latest version: 4.0.37

Steps to reproduce:
After launch, it prompted me to update to latest version. Click yes.
Wait till installer screen pops up.


Actual outcome:
Choose either Repair / Modify in the installer dialog windows(either one has the same result)
When finished, go back to software
Still prompted me to update
Auto-update seems failed


Expected outcome:
1. The installer should simply do the update (instead of asking repair / modify)
2. It should be able to update to latest version
