# Troubleshooting

> Fix common TPC CLI install, login, and update problems.

# Troubleshooting

## `tpc` command not found

* Open a new shell after installation.
* Check whether the installer added the binary directory to your `PATH`.
* Run the installer again and watch for shell profile update instructions.
* On Windows, `PATH` changes only apply to new PowerShell or cmd sessions.

## Login completes in the browser but CLI does not update

* Retry `tpc auth login`
* complete the device flow in the same machine where the CLI is running
* check whether your browser blocked the callback or redirected into a stale session

## Update does not find a release

* run `tpc update --check`
* confirm you are on the expected channel or pinned version
* if you installed a prerelease, make sure that prerelease metadata exists
