Installing and Launching Tex

System Requirements

Component	Requirement
OS	Windows 10 or later
Architecture	x64 only
.NET runtime	.NET 8 (bundled with the installer — no separate install)
Disk	~200 MB for the self-contained build plus language data
Display	1366 x 768 minimum; DPI-aware

Tip

Warning — Tex is an x64-only build. The ScreenRecorderLib native dependency pins the process to win-x64, so there is no 32-bit or ARM64 version. Installing on an unsupported architecture will fail at launch.

Installation

Tex ships as a WiX-generated MSI.

Run the Tex installer MSI provided by your administrator.
Accept the EULA prompt in the installer.
Choose an install location (the default is Program Files).
Finish the installer. The Tex shortcut is placed in the Start menu.

On first launch, Tex creates its per-user application folder:

%APPDATA%\Tex\
    settings.json            — all preferences
    capture_history.json     — persisted capture metadata
    crashes\                 — unhandled-exception reports

The installed executable lives under the install path chosen by the MSI (typically C:\Program Files\Tex\Tex.Wpf.exe). In a developer build, the binary is at src\Tex.Wpf\bin\x64\Debug\net8.0-windows\win-x64\Tex.Wpf.exe.

Default Save Locations

Content	Default folder	Setting to override
Images	`%USERPROFILE%\Pictures\Tex`	`Save.SaveFolder`
Recordings	`%USERPROFILE%\Videos\Tex`	`Recording.SaveFolder`

Both folders are created on demand the first time Tex writes to them.

Launch Arguments

Tex accepts three optional command-line arguments, all emitted by the auto-updater — you should not normally pass them yourself.

Argument	Purpose
`--post-update`	Relaunch after an update installed; shows an update-complete notification
`--update-failed --error-code=<n>`	Update install failed; shows an error notification with the given code
`--update-cancelled`	User cancelled the update; shows a cancellation notification
