  • I have made a windows application using Visual Studio 2010 and .NET 4.0. But the system on which the application has to run has .NET framework 1.1 installed on it. The normal user is not authorized to install anything on the system (company system).

    Is there any way of having a compatibility such that the .NET 4.0 application can be run on a system having .NET 1.1?

  • Hi Abhishek Das NTU,

    Thank you for your post.

    I have made a windows application using Visual Studio 2010 and .NET 4.0. But the system on which the application has to run has .NET framework 1.1 installed on it. The normal user is not authorized to install anything on the system (company system).

    Is there any way of having a compatibility such that the .NET 4.0 application can be run on a system having .NET 1.1?

    If I install .NEt 3.5 SP1, and then develop the application, will the application work on a system that has only .NET 1.1 installed?

    The .NET Framework has two main components: the common language runtime (CLR) and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework. .NET Framework 3.5 uses CLR version 2.0 and so does .NET Framework 2.0 or 3.0, while .NET framework 1.1 uses v1.1, .NET framework 4.0 uses v4.0.

    The compatibility goal for the .Net Framework is that applications and components from previous versions should work smoothly on the latest .Net Framework, except for a set of known changes.
    Thus, for your concern, to make your .NET 4.0 application run properly and stable on the target machine, you should install .NET 4.0 on it to support your application.

    Hope this helps! If you have any concern, please feel free to let me know.

  • Hi,

    You can't run Applications built using .NET 4 in a system that have .NET 1.1. The new versions of .NET have lot of new features that are incompatible with previous versions. You can seewhat is new in .NET 4.

    But if you change the target framework when you create the application you can run it. Visual Studio 2010 includes only the .NET Framework 4. To target earlier versions of the .NET Framework, you must have the .NET Framework 3.5 SP1 installed. To download and install the .NET Framework 3.5 SP1, see Microsoft .NET Framework 3.5 Service Pack 1 on the Microsoft Download Center Web site

    Good luck.

    HI, Yichun Chen

    I have a soft named Evernote (v3.5) that need .Net 3.5 to run,  and I installed .Net 4.0 on my computer, but when I run Evernote, it pops up a message box saying that"Evernote.exe - .Net Framework Initialization Error:  Unable to find a version of the runtime to run this application".

    What's going on? Is there a possibility that .Net 4.0 is not compatible with lower versions?

    Best regards

    An application developed on a computer with .NET 3.5 SP1 will not run on a computer with only .NET 1.1 installed unless you target the build for the earlier version of the .NET framework. Instructions on how to target an earlier version of the framework can be found here: http://msdn.microsoft.com/en-us/library/bb398202.aspx 
    Just because the code works, doesn't mean it is good code.

  • .NET Framework v3.5 is an *extension* of v2.0. 2.0/3.0/3.5 are a *single framework".

    The machine "on machines with 4.0 AND 3.5 everything works fine." *has 2.0 on it, so the app works.

    Your only option is to install 2.0 on the machine that has 4.0 only. Then, the 2.0 app will work.
