Since Remote Desktop Manager version 2023.1.7, it is possible to set a custom download path for Devolutions Updater instead of downloading in %TEMP%. It can be configured in two ways.
Go to File – Settings – Paths and enter a Custom download path in the field.

- In the Help tab, click on Check for Updates.  
- If Remote Desktop Manager can be updated, the Update Available pane will open. From there, click on Download, then select one of these options: - Download this version and install now: Devolutions Updater will open right now. 
- Download this version and install when application is closed: Devolutions Updater will open after closing Remote Desktop Manager.  
 
- When the Devolutions Updater window appears, click on Options.  
- Enter the Custom download path of your choice, then click Close.  
- Click on Update and follow the standard update process.
