(Case 00369292)
Helen,
The ActivStudio software can be installed in Windows 2000/XP (Professional or Home) and Vista Home. It will not work with Windows 7
Do be advised that we no longer provide support for the ActivStudio software; flipcharts made in that software can be opened with the ActivInspire software, the latest version of which can be downloaded from this page on Promethean Planet.
