https://www.microsoft.com/en-us/downloa ... x?id=15155You want this one for X64 Windows - SyncToySetupPackage_v21_x64.exe
I know nothing about FreeFileSync. I can, however, recommend a program that isn't free - Goodsync.
http://www.goodsync.com/lp?frm=gsp-012&affid=ems20It is a free trial, not free. $30 for a license. If you download from Download.com (the trial) be *very* careful when installing as download.com bundles a load of adware with what it serves up. Uncheck everything and don't allow anything to install except for Goodsync.
