How to detect if it’s First install, Uninstall repair etc.

Hi

How to detect if it’s First install, Uninstall repair etc. ?
I’m aware of the Installed, REMOVE, REINSTALL properties but still it’s not clear how to detect the exact way action is done, For example:
First install can be done with Full UI or in silent mode,
Repair can be done under “Programs and Features” and click Repair or Click Change and then choose repair or even run same setup again enter maintenance mode and then choose repair.
Uninstall is same as the above.
So how can I know in what way Modify or Repair are done ?
Also if I have CA that run on Uninstall I guess it should be in UI and exe sequence so how can I make sure they don’t run twice ?

Thanks.
