# Transmutr's window is blank

If the Transmutr window opens but stays empty or black, try the following.

## Windows

1. Install current **Microsoft Visual C++ Redistributables** (x64), including recent 2015–2022 packages from Microsoft’s download site.
2. Confirm the install folder is writable by your user account ( `%LOCALAPPDATA%\Transmutr\`).
3. Update your GPU drivers.
4. Restart the computer and launch Transmutr again.

## macOS

1. Confirm your Mac is Apple Silicon.
2. Grant any prompted privacy / accessibility permissions.
3. Move the app back to `/Applications` if you run it from Downloads only.

## Still blank?

1. Open **Options → Open log folder** if the UI is partially usable, or locate logs under the app’s data directory.
2. Email <transmutr@lindale.io> with your OS version, GPU, and logs.
