    Little Snitch has recently asked me if I'll allow "SLRuntimeLoader" to connect to go.Microsoft.com on port 80 (http). I don't have any Microsoft software installed and have no idea what this is. Unfortunately nothing useful comes up when doing a Google for it + "Mac" (or "OSX" either).
    So far I've told Little Snitch to deny it just to be on the safe side and have had no adverse affect.

    Do you have a Canon printer/scanner? Some of the Google hits suggest it's part of Canon printer driver.

    It's almost certainly not doing anything harmful. Reputable companies would face legal challenges if they were sending your personal details back to HQ. It's almost certainly just checking that it's up-to-date.

    All Little Snitch makes you do is worry about perfectly innocent network connections.

    Yes, I did indeed install a whole suite of Canon digital camera software, so that must be it (I don't have any Canon printer or scanner though).
    Thanks for clearing this up.

    Hi, this started popping up on my system every time I log in after installing some Canon DSL software, specifically Imagebrowser EX, which requires SilverLight to function (why, Canon, WHY?).

    Since I don't want MS software on my system (especially not Silverlight), I killed the install process, since Canon doesn't give you a chance to cancel when you get to the point where it installs Silverlight.

    Somewhere, there is something set, perhaps in a startup file, that keeps trying to re-run the SL install process.

    Should I find out how to get rid of it, I'll post that.

    SLRuntimeLoader -what loads it

    Looks like it all starts with:


    That launches:
    /Applications/Canon Utilities/ImageBrowser EX/ExtApp/MFManager.app

    Which must launch:
    /Applications/Canon Utilities/ImageBrowser EX/ExtApp/MFManager.app/Contents/Resources/SLRunTimeLoader.app

    which contains the executable.
