New installer "PlayOnline & Tetra Master.msi" error

[Alhanelem]

There is no EU law i've ever heard of that prevents downloading of anything at the windows or hardware level.. There are downloads that are illegal, yes, but they can't physically prevent you from downloading them, only get you in trouble for doing it.

I was having some odd crashes this morning, so decided to re-install. That was a mistake. It's complaining about the Tetramaster.msi now and I've tried multiple things. I've uninstalled and reinstalled multiple times, restarted the pc, I've tried manually deleting registry files after uninstalls. Nothing. SE why is Tetramasters being referenced in anything nowadays? Can't it just be removed entirely from the install process?

EDIT: I was able to get past this issue; I had to open up my Registry Editor, CTRL+F, and search and delete EVERY registry entry that included Playonline or tetramaster...

Was this with the current installer available via playonline.com?

It indeed does not include Tetra Master, so I guess it's possible some old registry entries could trip things up...
