Generally the advice I'd give with an error message like this is to look at the **windows\_package** resource documentation: [https://docs.chef.io/resource\_windows\_package.html](https://docs.chef.io/resource_windows_package.html) ...

If Chef cannot detect the package type to install, you need to specify it using the `installer_type` property (most likely, setting it to `:custom`) and also provide the relevant unattended options (e.g. `options '/q'`).

**But** it looks like you are installing Autologon, as in [https://docs.microsoft.com/en-us/sysinternals/downloads/autologon](https://docs.microsoft.com/en-us/sysinternals/downloads/autologon) - in this case it's more likely that Autologon.exe is the actual executable rather than an installer, and you either need to run it once with the /accepteula flag, or set the following registry key before the first run:

```auto
[HKEY_CURRENT_USER\Software\Sysinternals\Autologon]
"EulaAccepted"=dword:00000001

```

It might be better/easier in your case to install from the chocolatey package autologon: [https://chocolatey.org/packages/autologon](https://chocolatey.org/packages/autologon) where this is all done for you.
