## Please note: Template replacements don't work in this file. They are provided with default defines like
## mentioned underneath.
## If the keyword is not defined, "wails_tools.nsh" will populate them with the values from ProjectInfo.
## If they are defined here, "wails_tools.nsh" will not touch them. This allows to use this project.nsi manually
## from outside of Wails for debugging and development of the installer.
##
## For development first make a wails nsis build to populate the "wails_tools.nsh":
## > wails build --target windows/amd64 --nsis
## Then you can call makensis on this file with specifying the path to your binary:
## For a AMD64 only installer:
## > makensis -DARG_WAILS_AMD64_BINARY=..\..\bin\app.exe
## For a ARM64 only installer:
## > makensis -DARG_WAILS_ARM64_BINARY=..\..\bin\app.exe
## For a installer with both architectures:
## > makensis -DARG_WAILS_AMD64_BINARY=..\..\bin\app-amd64.exe -DARG_WAILS_ARM64_BINARY=..\..\bin\app-arm64.exe
