Upgrade with 2.60 and new MPLAB problems

[sinoteq]

Hi all,
Bought the PBP 2.60 upgrade and installed it on my new laptop running Windows XP service pack 2. Also installed the MPLAB version from the PBP CD. The problem I am having is that the PBP language suit is not listed in MPLAB. I have tried the special program that is included to register MPLAB add-on but it refuses to run. I only get an error message saying that the program is incorrectly installed, please try again. And I have tried again and again

Have anyone seen this problem before? Any easy fix for it?

Why have Microchip removed the support for PBP?

Thanks
Mike
