Most definetely this is not the case. Your windows box is of what's know as i386 architecture. It uses the Intel 80386 instruction set and architecture. Newer 64 bit PCs are the x64 architecture. Your PDA is a totally different processor, ARM, MIPS are two that come to mind. Apps compiled in i386 machine code use totally different instruction sets than the ARM CPU on your PDA...JP12687 said:theoreticly you can install any program on a windows based PDA, As it is i convert my plots to PDF and put them on my pda, i want to try installing lightwright as well.
