0x80070643 - Fatal error during installation.

I found another thread on this forum with the exact thread title, but it died out with no resolution and I had no permission to post in the thread.

Anyone know the resolution?

I just uninstalled PoE on my C:\ drive so I can re-install it on a new SSD I installed. Now I can't install the game.

Still failing here. Reboot didn't help.

A work around is to install the game through steam. Something is wrong with the msi installer straight from the pathofexile.com website.

I had zero issues with all my other games when I was migrating them to another hard drive.

This is the fix!
