You can't force anything, because the Dell Windows DVD you received is Vista 32-bit only. That is what you bought and was included when you bought your PC.
Also, 64-bit OS is only useful if you have more than 4GB of RAM.
OEM media contains only the version you ordered (and Dell won't provide anything other than what you ordered). Your key is valid for either one, but you must obtain the 64-bit media on your own. You can buy or borrow a Dell 64-bit DVD or you can use "retail" media to install, then activate over the phone using your Product Key.
This will instruct you in how to download 64 bit installation files and make a recovery USB as well as backup and restore the Dell OEM Product Activation.
