This document outlines the required prerequisites and setup steps before installing the Loadmill Desktop App on a Windows system. Ensure these requirements are met to avoid installation or runtime issues.
Operating System: Windows 10 or Windows 11 (64-bit)
Processor: Intel i3 or higher / AMD equivalent
Memory: Minimum 4 GB RAM (8 GB recommended)
Disk Space: At least 500 MB free space for installation plus additional space for captured HAR data and logs

Download the latest version of Loadmill desktop app for Windows from here
Double-click to run the setup
App will get installed in the following folder:
C:\Users\<username>\AppData\Local\desktop_app
When capturing HTTPS traffic (from browsers or mobile devices), Loadmill installs a local root certificate to decrypt HTTPS traffic
During installation, accept the certificate prompt to allow HTTPS capture
If using for mobile capture: export and install the certificate on the mobile device via Wi-Fi proxy configuration
Ensure both desktop and mobile device are on the same Wi-Fi network for proper capture
Allow outbound HTTPS (TCP port 443) to Loadmill’s cloud endpoints
Ensure that any corporate VPNs or firewalls do not block the Loadmill app executable or proxy ports
For capturing mobile traffic, verify the device proxy is configured to the desktop app’s IP and port (shown within the app)
Log files:
C:\Users\<username>\AppData\Roaming\Loadmill\logs
Configuration and captured data:
Stored under the app’s user data directory in AppData\Roaming\Loadmill
