In PowerShell make sure that electron and all dependencies are present:

# from the electron-ui folder
npm install --runtime=electron --target=1.7.6

Verify that the wallet runs with npm start.

Build script

Signing

In order to sign the installation packages during the build:

Install signtool from the windows 10 SDK and set the path to $signtool in config.ps1.
Also in config.ps1, update the Sign-Item function with signing certificate specifics.

(If a signing certificate isn't found signing will be skipped)

Building

Edit the version number in config.ps1.
Make sure all prerequisite executables are downloaded and placed in the prerequisites folder. Refer to pre-reqs readme.md for details.

# from the electron-wix folder
.\rebuild-all.ps1

The various other build scripts can be used to build individual packages. MSI's and the full installer executable will be in the electron-wix\build folder.

Machine-wide installation

The intaller executable cannot be used for per-machine installations and by default the MSIs are per user. In order to install per machine, run the following from an elevated command prompt:

# replace the msi name with the current version
msiexec /i <path_to_msi> MSIINSTALLPERUSER="" ALLUSERS=1
