We’ve begun covering 64-bit computing, due to the current availability of 64-bit hardware, and the slowly increasing availability of 64-bit software. See, for example:
Feedback On 64-bit Hard/Software
OS Swaps; 64-bit CPUs
To complement and extend the above, here’s another reader’s real-life experience with a 64-bit setup:
Fred: I just yesterday communicated with zone alarm about a 64 bit version. since I just upgraded to win xp 64. ( it is really faster, and has a ie6 64bit. and zonelabs said there was no 64 bit version….seems as though they better rethink that.
also roxio 7.5 will not work on win 64 either. and nothing on their site about upgrades… —Larry Ravencraft
