Background - String Path to the background for the DMG window. Background image should be of size 658 × 498. Icon - String Path to the icon to use for the app in the DMG window. Overwrite - Boolean Overwrite an existing DMG file if if already exists. Debug - Boolean Enable debug message output. Out - String The directory to put the DMG into. In this article, you will learn how to create an installer for windows using the electron-winstaller module which uses Squirrel, the installation and update framework for Windows desktop apps. Prepare your work area. And with this, we don't mean that you should clean your computer. In our project we use or install two external libraries: mysql and pretty-bytes for our installer to add these libraries remember to have them in 'dependencies' and libraries like Electron Builder that we are using to create the installer we do not need them in the installer so they can go in 'devDependencies' or just do not add it in the. Window - The DMG windows position and size. X = 400 Number - The X position relative to left of the screen. Y = 100 Number - The Y position relative to top of the screen. Width Number - The width. Defaults to background image width or 540. Height Number - The height.
The top-level nsis key contains set of options instructing electron-builder on how it should build NSIS target (default target for Windows).
These options also applicable for Web installer, use top-level
nsisWeb key.
Inherited from
TargetSpecificOptions :
Unicode enabled by default. Large strings are supported (maximum string length of 8192 bytes instead of the default of 1024 bytes).
32 bit + 64 bit¶
If you build both ia32 and x64 arch (
--x64 --ia32 ), you in any case get one installer. Appropriate arch will be installed automatically.The same applied to web installer (nsis-web target).
Web Installer¶
To build web installer, set target to
nsis-web . Web Installer automatically detects OS architecture and downloads corresponding package file. So, user don’t need to guess what installer to download and in the same time you don’t bundle package files for all architectures in the one installer (as in case of default nsis target). It doesn’t matter for common Electron application (due to superb LZMA compression, size difference is acceptable), but if your application is huge, Web Installer is a solution.
If for some reasons web installer cannot download (antivirus, offline):

Custom NSIS script¶
Two options are available — include and script.
script allows you to provide completely different NSIS script. For most cases it is not required as you need only to customise some aspects, but still use well-tested and maintained default NSIS script. So, include is recommended.
Keep in mind — if you customize NSIS script, you should always state about it in the issue reports. Hp easy scan dmg download for windows 10. And don’t expect that your issue will be resolved.
Use
${isUpdated} .
GUID vs Application Name¶
Windows requires to use registry keys (e.g. INSTALL/UNINSTALL info). Squirrel.Windows simply uses application name as key.But it is not robust — Google can use key Google Chrome SxS, because it is a Google.
So, it is better to use GUID.You are not forced to explicitly specify it — name-based UUID v5 will be generated from your appId or name.It means that you should not change appId once your application in use (or name if
appId was not set). Application product name (title) or description can be safely changed.
You can explicitly set guid using option nsis.guid, but it is not recommended — consider using appId.
It is also important to set the Application User Model ID (AUMID) to the appId of the application, in order for notifications on Windows 8/8.1 to function and for Window 10 notifications to display the app icon within the notifications by default. The AUMID should be set within the Main process and before any BrowserWindows have been opened, it is normally the first piece of code executed:
app.setAppUserModelId(appId)
Portable¶
To build portable app, set target to
portable (or pass --win portable ).
For portable app, following environment variables are available:
