Razer software will not run, will not reinstall

I delete drivers, update drivers driver via driver easy, I try and reinstall Synapse (TWICE) it goes all the way through and hangs on final step with this error.

I like Razer hardware, but your software is buggy garbage. 1-2 times a month it just quits working.

Fire you software guys, get some that know how to debug their code.

In the mean time, please help fix you buggy software. How do I get it to instal? That would be a start.
