Nullsoft Installation System is a pretty small, efficient, capable installation system for win32.

What's new

major internal changes, much testing required --
Added /FILESONLY option to CopyFiles
Made FileRead stop on nuls.
Added FileReadByte and FileWriteByte.
Added Return instruction.
Restructured how code is called internally (Ret instruction rather than code lengths)
Made jumps absolute instead of relative.
Added GetFunctionAddress and GetLabelAddress, extended Call, Goto and Goto-like instructions to take user variables as jump targets.
