When installing Process Modeling 5 (pm52en_r11179.exe) on a Vista machine I get the following error messaging that stop the installation: "The process modeler requireds the .NET Framework 2.0 to be installed...". But Vista are by default having the .NET 3.5, and 2.0 canīt be installed? (see also attached file on error)

Is there a different installation file for Vista systems or have you seen this problem before?

thanks
