The first 4 options are used to compare file version information: you can determine whether a file already present on the destination computer is more recent or not (and consequently whether it should be overwritten or not). This has to be used with the conditional variables and a Conditional If block for instance.
"fiTestEXEx86" lets you test whether an executable program file is 32-bit or 64-bit. It works on any Windows version.
