It's nowhere specified what are the supported Windows versions for DataLink Viewer version 2011. I've downloaded the user guide, and it says only this related to app compatibility: DataLink Viewer 2011 uses the Crystal 2011 runtime components and allows you to run Crystal reports from version 7, 8, 8.5, 9, 10, XI, 2008, 2011, 2013, and 2016.
