I have tried both 8100M_PBr4[1].2.1_rel148_PL2.3.0.77_A4.2.1.94_Rogers.exe and 8100M_PBr4.5.0_rel139_PL2.7.0.85_A4.5.0.102_Rogers .exe which both seem ask the usual questions and finish successfully but do not show up in the Start menu or Programs search. Not surprising since I cannot find "C:\Program Files\Research In Motion\BlackBerry\DesktopMgr.exe" either.

Despite getting the 'Insufficient charge ...' message when connecting via USB, the drivers seems to be loading OK and I can see my Pearl as a mass storage device.

As for Bluetooth, forget it. There are too many tales of woe if you search Windows 7 bluetooth so I will be reverting back to XP soon.
