Solved! Update hp pavilion dv600 to 64 bit

[tanganyikadave]

Neee help updating my hp pavilion dv600 from 32 bit to 64 since it is impossible to install a 64 bit version of Windows 7 ultimate. It shows the error "this cpu is not compatible with 64 bit"
Thank you

There has never been an upgrade from 32 to 64 bits. It requires a fresh OS install. But since the maximum memory that laptop supports is 2GB upgrading to a 64bit OS won't benefit you.
