Running a PC with more then 4 GB RAM it is necessary to use the 64-bit version of Vista. I think that a lot of people will change to this version if they want to add more memory. Therefore I hope You will provide a 64 bit driver for PCSU1000 as soon as possible.
Thank you for your comment. Indeed the 4 GB RAM limit may push the users to the 64 bit Vista version…
