If you also have Premium Remote Control Client on a device, that also can be removed.

    %userprofile%\AppData\Local\ISL Online Cache

  • Then go into RegEdit and remove the following keys:

    Computer\HKEY_CURRENT_USER\Software\ISL Online

    Computer\HKEY_USERS\.DEFAULT\Software\ISL Online  


Note: Some folders or reg keys may not be found and a reboot is preferred.

Reinstalling PRC on an End Device

If you wish to reinstall PRC, you will want to do the following steps

  • Go to the Device Overview Page
  • Click on Get Latest Assets on the right-hand menu
    • Or wait for asset collection to run naturally every four hours
  • Wait 10-15 minutes for the asset collection to complete
  • Select Premium Remote Control under the Management section of the right-hand menu
  • Click on Install
    • If this has not cleared, asset collection has not been completed
  • Wait another 5-10 minutes and refresh the page to see connect prompt

If the reinstall of PRC fails, restart the end device and attempt again.
