Unfortunately the sales/tech person from the store was right in telling you upgrading from a 32bit OS to a 64bit OS is not possible. If you are currently running a 32bit operating system you will need to purchase the full version 64bit edition. You are most likely going from Windows XP 32 to Windows 7 64 like a lot of other individuals out there (it’s quite common now).
To keep things simple the reason behind the inability to switch between 32 bit and 64 bit is the architecture itself. Although Windows 7 32bit and Windows 7 64bit look and feel like the same operating system, under the hood there are drastic differences in how they handle the system. Those differences are just too much to make an upgrade to transition a machine from a 32 bit architecture to the newer 64 bit. A more detailed description of the differences and incompatibilities between the architectures might get a writeup at a later point but that should briefly explain why it can’t be done.
Before purchasing the newer version of your OS, be sure to do a full backup of your computer. You are going to need it when the new operating system installs over the one currently installed. You will lose everything currently on the hard drive so make sure the backups work!
You did remember to check if your hardware supports 64 bit processing, right?
