iSyncr requires .NET 2.0 or higher on your system. In most cases, your computer will already have .NET 2.0 or higher. Unfortunately, Windows 8 does not appear to be shipping with support for .NET 2.0 and higher. In either case, installing .NET 3.5 is the recommended action.

If we're running Windows 10, although you may have a higher .NET version (3.5+) it is not backwards compatible to work with iSyncr Desktop; install .NET 3.5 from below.

You can download .NET 3.5 from the following page. Or just use the following link. Still having trouble? Contact Support
