I have every update of APG as they are released.. APG does not kill off previous versions so why should PTP..
Both installers are based on same code, so they should react the same way.
Ok.. To be honest, I am fed up with any PTP updates killing off my custom HTML files and the Live Pano licence.. I just updated from a RC1 to the stable version.. V2.2..
Where do you put your "custom HTML files" ?
They should be in your "User directory" and a new install does nothing in this directory.
