SyncBackSE, and SyncBackPro are different programs and can be
installed at the same time on the same computer. SyncBackSE and
SyncBackPro will expire and cease to work after the trial period expires
unless a license is purchased. They will not become freeware. Also,
SyncBackFree is not the evaluation version of SyncBackSE or SyncBackPro. Certain aspects of the commercial versions' enhanced functionality mean they may behave differently to the freeware version in recent versions of Windows. It is always recommended to download a trial of the commercial version(s) if they are what you envisage using in the future.
To evaluate SyncBackSE download the fully functional 30-day trial now.
To evaluate SyncBackPro download the fully functional 30-day trial now.
There is no need to uninstall the 'trial' and download a 'registered' version if you purchase. The software simply switches out of trial mode if you enter an appropriate serial (including re-activating any expired install).
