  4. Should the status of either or both services be Stopped, attempt to restart the halted service(s) by right-clicking on the service name and selecting Start.
  5. Should the service(s) fail to start, or if they start only to stop shortly after, consider rebooting your computer. This issue may stem from recent installations of other software or Windows updates that necessitate a system reboot.
  6. If you continue to have issues with Scout, uninstall Scout by selecting Probax Scout Uninstaller from the Start Menu:
    1. Once Scout is uninstalled, delete the following folder:
      1. C:\Program Files (x86)\Probax Scout
    2. Then, delete the contents of the following Temp folders:
      1. %localappdata%\Temp 
      2. C:\Windows\Temp\
    3. Next, reinstall Probax Scout and link it with MSP Backup.

Q2. Is it necessary to whitelist Scout for optimal functionality?

Absolutely. For Scout to operate seamlessly, it's imperative that you whitelist Scout along with all its associated properties in your antivirus and firewall configurations. Following the installation of Scout, if there's a noticeable delay in its check-in times, it could indicate a need for whitelisting. To ensure uninterrupted service, we recommend whitelisting the following:

    • Folders:
      C:\Program Files (x86)\Probax Scout\
    • Files:
      C:\Program Files (x86)\Probax Scout\Probax-Scout-Watchdog.exe
      C:\Program Files (x86)\Probax Scout\Probax-Scout-Controller.exe
      C:\Program Files (x86)\Probax Scout\Probax-Scout.exe
    • Services:

      Probax Scout
    • Processes:
    • Domains:
  • Ports:
    TCP 443


    Q3. Can I install Scout on a 32-bit operating system?
