Updating from 4.1.6 to 4.3.1

I got problem with updating to the recent version. I am Lifetime user. Appreciated if you could produce 4.3 installer.

What’s the problem? Error message?

They don't post the installers on the forums for obvious reasons. If you've encountered issues with the updates or issues with the software keeping it from actually working correctly, you need to contact support rather than posting on the forums. That will get you more clarified answers I'm sure.
