Upgrade: SyncToy engine has been re-architected. As a result, it is important to run all folder pairs before and after an upgrade from a previous version of SyncToy.
SQL Server Compact Edition: SQL Server Compact Edition is a client side database that SyncToy uses to store its metadata. As a part of the SyncToy installation, SQL Server Compact Edition 3.1 will be installed on the target machine.
Installation: If SyncToy 2.0 Beta is installed using an account which is different than the one that was used to install previous versions of SyncToy, then the previous version will not be uninstalled. In this case, it is recommended that users uninstall the previous version using the previously used user account before installing SyncToy 2.0 Beta.
