Seems the new installer is quite a robust bit of soft, except for one thing..
..when I use the menu to install a program, when I click on the menu (PAP) after the installer has finished it crashes and sends to MS Error reporting.
This only happens after the installer finishes eg, TB or FF and only while the installer page is still open.
My feeling is it is to do with Vista's "did this program install correctly?" and shows that PAP and its' app's arent in full compliance with MS.
Hopefully someone here can ask microsoft about these bugs since all I can do is send them off. There is nothing more I can do except report it.
This isn't trolling it's bonafide bug reporting so take it as you wish.
