To test ObjectMake, you must have an installation of Synergy 6.5 SP2 with patch 6.5 SP2 01, or its replacement, applied. Patch 6.5 SP2 01 includes an important change to ObjectMake that you need to use ObjectMake with Release 7.1.
If you are running Synergy Release 6.4, you do not need to upgrade your data to release 6.5 SP2. However, you do need to install 6.5 SP2 with patch 6.5 SP2 01, so that you can access files from that installation.
