Although you have 64 it, some older programmes and devices install and work OK in 32 bit. They appear in C: Programme Files (x84). I do not have an Epson, but if you look here you should be able to download the right drivers, be they 63 or 32 bit. If the machine is a little old, they are likely to be the 32 bit ones but that should not be a worry.See here:
