Windows 7: Migration of .Net applications

20 Jul 2010   #1

Migration of .Net applications

I tried to run some .Net Applications on W7.
This application was developped under XP with Visualstudio2005.
Application doesn't work.
The raison is perhaps that Microsoft .NET Framework 3.0 Redistributable Package is not installed on W7.
How can I know if this package ist already installed and wich version is installed?
Thanks in advance.

.NET Framework is included in Windows 7 as a feature. Go to Control Panel/Programs and Features and on left side click on Turn Windows Features On or Off and look for Microsoft .NET Framework 3.5.1. If it is checked or shaded then it should be installed. It includes version 2.0 - 3.5.1.
