# Install on Windows

A signed x64 installer, a standard Windows user, and a small first project.

## Verify the installer

Download Windows x64 from [Downloads](/downloads/). Compare the published SHA-256 using `Get-FileHash -Algorithm SHA256 <installer.exe>` in PowerShell. Inspect Properties → Digital Signatures, or use `Get-AuthenticodeSignature <installer.exe>`. Check the publisher and timestamp against the release information. Do not disable SmartScreen or ignore an invalid signature.

## Install and start

Run the verified installer. Allow only the documented installation changes. If the release requires an isolated execution runtime or a Windows feature restart, complete that step before enabling Agent. Start Workcell from its shortcut as your normal user, not from an elevated administrator shell.

## Check the first launch

Open the small starter project, verify that the viewport is visible and keep it paused. Check text size and keyboard focus. Follow [activation](/docs/activation/) when customer access is available. A graphics-driver or runtime error needs diagnosis; repeatedly launching older builds is not a repair.

## Update or remove

Use [updates and uninstall](/docs/updates-and-uninstall/). Keep projects outside the application directory. Support needs the version, Windows build and redacted error—not your license token or payment details.
