1) Let's make sure you have the latest SAS universal viewer: Download it at: https://support.sas.com/downloads/package.htm?pid=667 2) Also, please perform this check (From the SAS site): SAS Universal Viewer requires the Microsoft .NET Framework runtime 2.0 or later. To determine if you have the appropriate software, click Start->Settings->Control Panel. Windows XP users should look under Add or Remove Programs and Windows Vista users should look under Programs and Features. If Microsoft .NET is not listed, go to the Microsoft download Web site (http://www.microsoft.com/downloads) and search for .NET 2.0 or later under "All Downloads." Follow the instructions on the resulting page to download and install Microsoft .NET.
