    a couple of things to check:

    do you have Sync Framework installed on your server?

    does the platform of your Sync Framework installation match match the application platform? (i.e., 64bit Sync Fx for 64bit application, etc...)

    3ks,JuneT

    I had installed the Sync Framework(DatabaseProviders-v3.1-x86-CHS.msi,ProviderServices-v2.1-x86-CHS.msi,Synchronization-v2.1-x86-CHS.msi) on the internet server.

    I fixed the exception.

    fixed by set the local sqlsyncprovider and remote sqlsyncprovider MemoryDataCacheSize=1,BatchSpoolLocation=batch spool location Directory.

    =====================================================================

    i guess the exception will raise by sync the data size that is too big.

    you should get an out of memory exception if its related to memory and not COM error.
