nsisbi Files

NSISBI aims to remove the current 2GB limit found in NSIS. This version adds support for using a separate file for storing the install data, therefore allowing installer sizes up to a theoretical max size of 8EB. Single files are still limited to 2GB.

The compiler (makensis) is designed to run on 64 bit machines as this is the feature needed to make installers bigger than 2GB.

The command to use an external file is: SetExOutFile auto | off | on. The 'off' setting is the same as classic nsis (all-in-one installers). The 'on' setting forces creation of external files regardless of size (except zero data installers). The 'auto' setting is the default, so it creates all-in-one installers up to the 4GB limit, past this limit it switches to an external file for the data. The only down side is that solid compression is not supported, due to its design it just isn't feasible to add support.

An undocumented 'Target' command also exists that allows the target architecture to be selected. It is: Target cpu-charset. Valid values are: x86-ansi, x86-unicode, amd64-unicode.

Built on 16/01/2017 on Windows 10, using Visual Studio 2008 with the Windows 7 SDK. This version creates native 32 bit ansi installers as the default, you can also target 32 bit unicode installers, as well as 64 bit unicode installers. This is just a bugfix from the last version, the default target was wrongly set to amd64-unicode which I fixed (set to x86-ansi now). I also added cleaning of both x86 and amd64 to clean.bat.
