required Sync Framework components cannot be found... RRS feed

    I have been using SyncToy 2.0 for many months now, with no problems. (Dell GX260/1GB RAM/XP Pro SP3)

    A few days ago, I used it to sync a folder pair, no problems, closed SyncToy.

    Less than 15 minutes later, I remembered that I needed to run another folder pair, so I re-opened SyncToy, selected the folder pair, then clicked on Preview.

    An error dialog box opened: "The required Microsoft Sync Framework components cannot be found. Please re-run SyncToy 2.0 setup from the original location."

    Tried that, ran the 'Repair' option, no change. Tried 'Remove' then re-install, no change.

    Tried uninstall from Windows' Add/Remove Programs, also uninstalling the two Sync Framework apps (Runtime and Services), then re-install SyncToy, still no joy.

    Finally, I again uninstalled all, plus deleted the "%UserProfile%\Local Settings\Application Data\Microsoft\SyncToy\2.0" folders in each of my user profiles, then re-installed SyncToy.

    As expected my folder pairs are gone, but I get the same error when I click on "Create new folder pair"!

    I'm at a loss...The only thing I can think that I may have done before the error started, was to use Ccleaner as I frequently have in the past, to clean up the drives & registry.

    Anyone have any ideas? I'm thinking I either deleted a critical key by error, or I need to manually delete a corrupted key that's causing the problem...

    Any help would be appreciated!

    Hi -

    I am sorry but you have done everything that I could possibly think of as well in this situation. The only thing I would do is to uninstall everything and try to verify what you have left. Look through the registry for references to SyncToy and delete those ( changing registry keys can be harmful so if in doubt paste the key back here and I will try to verify that it is okay to delete it). Do you know how to check for assemblies in the GAC? If you can - verify that that Microsoft.Synchronization.dll and Microsoft.Synchronization.Microsoft.Synchronization.MetadataStorage.dll, Microsoft.Synchronization.Files.dll have all been removed.

    Let us know how it goes.

    Thanks

    I ran into the exact same error.    SyncToy 2.0 worked fine until a couple of months ago.   Maybe some Windows Update broke it.

    I'd love to solve this.   It's a great backup solution.

    Hi,

    I experienced the same problem, suddenly SyncToy 2.0 refused to work, "preview", "run" or "Create new folder pair" all produced the dreaded error message "The required Microsoft Sync Framework components cannot be found..."

    I also tried all of the suggested options, but nothing helped.

    I then created a test user (thus with a clean user profile) on the same computer, and SyncToy worked perfectly from there.
    So I figured the issue had to be situated somewhere in the user profile, either in the registry or in the user profile on disk.

    A search & fiddle in the registry didn't really help, so I started browsing through the user profile on disk.
    I then stumbled upon this particular file and renamed it, and from then on, SyncToy worked fine again.

    -> %LOCALAPPDATA%\filesync.metadata
    (on my vista computer the path is -> C:\Users\UserName\AppData\Local\filesync.metadata)
    (on WinXP, obviously the location will differ, I'm not sure what it is, but a file search will most likely reveal this)

    Hope this will help others as well.

    Cheers,
    Paul.

    Had the same problem on Windows 7. The fix by PaEgg worked great. Thanks!

    Just to add my two cents' worth.

    Had the problems described above, just out of the blue.

    Tried all the above stuff but what worked for me in the end was manually uninstalling "microsoft sync framework runtime v1.0 (x86)" and "microsoft sync framework services v1.0 (x86)" and then reinstalling SyncToy. There were also another two installations listed that were similar to the two mentioned here but these also had "native" in the title. I left them alone and it all seems to be working fine now.

    It's not until you lose this little app that you realize how brilliant it is.

    I put this issue on the backburner and kind of forgot about it (for a long time, obviously!), but I got back into it today and read your post, Paul.

    Your solution worked for me when nothing else would; I had tried uninstalling and reinstalling both Framework components and SyncToy until I was pulling my hair out, with no luck.

    However, as soon as I renamed the filesync.metadata file as you suggested, all was well again!!

    By the way, in Windows XP the file is in "\Documents and Settings\[user]\Local Settings\Application Data".

    Thanks for the tip, Paul!

    I came across the same issue and followed the answer suggested by Paul. It worked !! I have noticed that its because of a size limit of metadata file which when reaches 4 GB, the utility stops working. So if you simply copy and rename the old metadata file and create a fresh metadats file the problem gets resolved. Seems microsoft has put a limit on the size of metadata for syncToy. However needs to confirm this from Microsoft.

    Thanks

    Folks,

    I dont know what is going wrong now.

    - Clean install of SyncToy 2.1 x64

    - Windows 7 SP1 on i7

     

    I checked many threads. When i install SyncToy2.1, the 2 Sync Framework components are installed. Yet, when i go to create New Folder Pair, I get:

    SYNC: 11/27/2011 18:52:10:927: Starting SyncToy, version 2.1.0.0, built 10/19/2009 4:04:38 AM.
    SYNC: 11/27/2011 18:52:12:635: *** The required Microsoft Sync Framework components for SyncToy cannot be found. Please re-run SyncToy 2.1 setup from the original location.

    1. I did the repair steps on the 2 components, as mentioned above

    2. Confirmed, that i do not have the metadata file.. coz new install.

    3. SyncToy log is as shown above.

     

    ANY Pointers? This worked VERY WELL on my older XP machine.

    Old post but not a lot on this subject - I too had 4 "synctoy" installs. Two for x86 and two for x64. Uninstalled both, then reinstalled one of them - good to go now.
