Hello.

Every time I launch the latest version of Lightroom CC I get:  Unable to setup wf rtmfp notify pipe.  I have uninstalled, reinstalled and rebooted and the problem is still there.  Graphics processor acceleration is disabled as well.

Windows 10 64 bit

32 gb ram

2 tb free disk space

I do not use a vpn.

Can anyone assist.

Thank you

    Hi David,

    We've never seen this issue before, and unfortunately we cannot reproduce the behavior you've described. Something you could try is adding an exception to the Windows firewall for the Lightroom CC executable:

    1. Open the Windows Firewall from the control panel.
    2. Click on the “Advanced Settings” link on the left pane.
      Windows Firewall with Advanced security UI opens up.
    3. Click on the “Inbound Rules” option.
    4. On the  left pane, click on “New rule”.
    5. Under “Rule Type” select the option “Program” and click next.
    6. Select the option “This Program path”.
    7. Browse to the Lightroom CC executable location:
      C:\Program Files\Adobe\Adobe Lightroom CC\lightroomcc.exe
    8. Select the option “Allow the connection”.
    9. Click Next, do not change any option here and click Next again.
    10. Specify a name for this rule.
    11. Click Finish.

    If the above does not resolve the issue, you could try repeating these steps for lightroomcchelper.exe which is found adjacent to the Lightroom CC executable.

    Hopefully this resolves your issue.

    Thanks,

    Jeff

    I reinstalled the software as admin, added the exception to the Firewall and I'm running it as admin as well.

    This fixed the issue even in v1.1

    (however, using the software I discovered I can't live without my folder structure, therefore will try to change my subscription to Classic CC)

    The issue "Unable to setup WF RTMFP Notify Pipe" occurs when Lightroom CC is unable to initialize communication between the various Lightroom CC processes that run simultaneously on a user’s machine.

    Some users experience this issue when using a VPN because certain VPN services block all local network traffic that uses IPv6 (a type of internet protocol used by Lightroom CC for local process communication). Most VPNs can only route IPv4 network traffic, and so many VPNs disable IPv6 to ensure that no IPv6 traffic leaks out over your normal internet connection when you are connected to the VPN.

    Unfortunately, some VPNs have implemented this leak protection in such a way that it also erroneously blocks local network traffic that uses IPv6. This can prevent any app that uses IPv6 locally, even when not communicating with outside servers, from working properly.

    For users that encounter this issue and are using a VPN, there are two workarounds:

    1. Disable the VPN
    2. If it exists, then disable "IPv6 Leak Protection", or any similarly worded setting, in the VPN preferences. With this setting disabled, LrCC should work just fine.

    For users that are not using a VPN, it's likely that they have some other software installed that is preventing IPv6 network traffic. Likely candidates are firewall and anti-virus software. If you have such software installed, I'd advise you to disable it and then try launching LrCC. If this fixes the problem, then you will need to add some sort of exception to the anti-virus software for LrCC.

      Hello.

      This is the only way I can get Lightroom CC to work:

      1).  I turned off the Windows 10 Firewall (no third party firewall or anti-virus is used)

      2).  Launched Lightroom CC and I get a collage of my photos

      3).  Closed Lightroom CC

      4).  Turned Windows firewall back on

      5).  Launched Lightroom CC - and I get the same collage of my photos. 

      I do NOT use a VPN !!!!!!!  

      When I reboot, I have to go through this process again.

        Hi DavidJBier,

        Do you get to open the Lightroom CC app when you see the error "Unable to setup wf rtmfp notify pipe"? Could you please help us with the exact error message and a screenshot of the error pop-up menu?

        Thanks,

        Hello.

        When I launch the app, I get the normal Lightroom splash screen, then a spinning blue circle in the middle of the screen.  I get the error message if as soon as I hit Edit - Preferences.

        Please restore Lightroom preferences to default. See How to set Lightroom Classic CC preferences

        Let us know the outcome.
