 You can also use the steps from [above](https://rustdesk.com/docs/en/self-host/client-configuration/#setup-using-import-or-export) to export the string, remove any `=` at the start or end of the string. Restart RustDesk Client if settings don't show.
 
-### 5. Put config in rustdesk.exe file name (Windows only)
-
-Change `rustdesk.exe` to rustdesk-`host=<host-ip-or-name>,key=<public-key-string>`.exe, e.g. rustdesk-`host=192.168.1.137,key=xfdsfsd32=32`.exe. You can see the config result in the About Window below.

-As a `Pro` user you will be able to retrieve the whole encrypted string from the [web console](https://rustdesk.com/docs/en/self-host/rustdesk-server-pro/console/) then download and rename the RustDesk Client exe, you can upload this somewhere easy for your customers to use.

-You need to set both `host` and `key`, missing either one will not work.
-
-Optionally add a `,` (comma) character after the key, before the `.exe` part as a delimiter, to avoid the key being mangled if Windows or the browser renames the file when downloading duplicated names, e.g. `host=<host-ip-or-name>,key=<public-key-string>,.exe`.
-
-If there are invalid characters in the key which can not be used in a Windows file name, please remove the
-`id_ed25519` file from your server and restart `hbbs`/`hbbr`. This will cause the `id_ed25519.pub` file to regenerate. You may need to
-repeat this process until you get valid characters.

-#### Embrase config string with `--` in the name

-Please do not use `-licensed-` together with `--`, e.g. `rustdesk-licensed-{config-string}--.exe` does not work in version 1.2.3. We will fix it in version 1.2.4.
-{{% /notice %}}
-
-We have noticed that in some cases, when double downloaded, something like `copy (1)` is added to the end of the file name, and this ruins the config.
-
-By adding `--` at the end right after our config string, even if something is added to the file name, it won't corrupt the config string, and RustDesk will correctly retrieve it.
