Every feature,
and a guided tour.

Every installer starts here. Name your app, set its version, publisher and icon, add agreements as their own wizard steps, and enter support contacts that appear as a Support button in the wizard and in Windows.

• ◇Name, version, publisher, icon
• ◇Shown in Add or Remove Programs
• ◇License and EULA pages (text, Markdown, RTF)
• ◇Agreements with optional accept gate
• ◇Support links in wizard and Windows

Decide what you ship: .exe, .msi or both, for x64, ARM64 and x86, from one project. Pick the Windows and Windows Server releases you support, per architecture sources, install scope, rollback and Repair behavior in one place.

• ◇EXE and MSI for x64, ARM64 and x86
• ◇Native ARM64 application
• ◇Supported Windows and Server releases
• ◇Per architecture source directories
• ◇Per user or per machine install

Make sure a machine is ready before anything installs. Add checks for memory, screen size, a pending restart, a reachable URL or existing software. Each check blocks the install or only warns, in EXE and MSI, silent installs included.

• ◇Memory and screen size
• ◇No pending restart
• ◇URL reachability
• ◇Files, registry, .NET, Windows features
• ◇Block or warn, never on uninstall

Add files, folders or glob patterns and map them under the install directory. Folders open as live trees that follow your disk, and a right click excludes what should not ship. Per file controls cover permissions, registration and conditions.

• ◇Files, folders, and globs
• ◇Live folder trees with exclusions
• ◇Destination mapping
• ◇DLL registration and permissions
• ◇Per file conditions and features

Register your file types without replacing the default apps people already chose. Your app appears under Open with, each extension gets its description, icon, launch arguments and ProgID, and setup offers a Choose default apps button.

• ◇File extension associations
• ◇Registered under Open with
• ◇Existing default apps stay untouched
• ◇Choose default apps button after setup
• ◇Optional, customers can switch off

Decide what is optional. Build a hierarchy of features with dependencies and exclusive groups, and define setup types like Recommended, Minimal and Custom that each preselect a set of components.

• ◇Optional components
• ◇Nested feature groups
• ◇Feature dependencies
• ◇Exclusive (radio) groups
• ◇Named setup type presets

Place shortcuts in the Start Menu, on the Desktop, in Quick Launch or at Startup. Optional locations appear on a Select Additional Tasks page, and targets are suggested from the files you added.

• ◇Start Menu and Desktop
• ◇Quick Launch and Startup
• ◇Optional Additional Tasks page
• ◇Custom labels for optional tasks
• ◇Targets suggested from your files

Know the runtimes your app needs will be there. Byte Installer detects them with registry, file, OS and .NET probes, the same way in EXE and MSI, then installs what is missing from a pinned URL or bundled payload.

• ◇Registry, file, OS, .NET detection
• ◇Same detection in EXE and MSI
• ◇Install from URL or bundled payload
• ◇Per architecture sources, SHA 256 pinned
• ◇Embedded at build time for offline installs

If your app listens on a port, declare the firewall rules it needs. Pick the program from your Files list and the rule follows that file, its conditions and components. Rules are added at install and removed at uninstall.

• ◇Inbound and outbound rules
• ◇Allow and block
• ◇Program picked from your Files
• ◇Port, protocol, IP, service, profiles
• ◇Conflict resolution behavior

Run scripts at pre install, post install, pre uninstall or post uninstall. Lua is embedded for portable logic, batch and PowerShell are there when you prefer them, and post install and pre uninstall hooks ship inside your .msi too.

• ◇Four lifecycle events
• ◇Lua, batch, PowerShell, shell
• ◇Batch and PowerShell hooks in MSI
• ◇Per hook timeout
• ◇Platform scoping

Make the installer yours. Pick one of seven wizard layouts, light or dark, your accent color and welcome image, and rewrite the Welcome and Finish pages while the live preview renders the real wizard and MSI dialogs.

• ◇Seven wizard layouts
• ◇Light, dark, system theme
• ◇Accent color and welcome image
• ◇Custom CSS
• ◇Live preview of wizard and MSI dialogs

Set output options per target, configure signing and build. A preflight check validates your certificate in under half a second, every referenced file is checked before packing, and the signature is verified after signing.

• ◇Per target output settings
• ◇Code signing profile
• ◇Every file checked before packing
• ◇Signature verified after signing
• ◇Compression and payload deduplication
