  the application.
  I'm assuming there is a configuration file that allows me to change things about how the application is compiled.
  
  I want to enable our framework 1.1 application to run under .net framework 2.0.

  You can still download v1.1 of the .NET framework:

  You can use the <supportedRuntime> and <requiredRuntime> in your application configuration file to specify what version(s) you require/support.
  Here is some information on how how to do this:

  Hello,
  
  I too am having a similar problem, but I am not currently doing development work. Trying to run/install applicationss built on .net versions < 2.0. For instance I tried to install the visio connector for the MSBSA (Microsoft Baseline Security Analyzer) and was told that version 1.1.4xxx needed to be installed for me to install the connector. This isn't the only instance of theis problem occurring, just the most recent.
  
  Any help any one can provide would be very helpful.

  Hello Johan,
  Where can I find the configuration file in VB2003

  There should be a template for adding a new configuration file to your project (project -> add new item). Make sure that you keep the name app.config for the file.

  Have you looked at the links I gave in my earlier post about using the supportedRuntime element.

  Best regards,
  Johan Stenberg

  Which configuration file devenv.exe.config, your application's configuration file or machine.config

  First for your Question Ruud.  The Setup.exe that is included with built setup Projects installs windows installer if it is not there.  You will still need to change the supported runtimes of the launch condition to include 2.0.50727 in the setup project launch condition editor, (it is semi colon delimited).  I don't believe there is a launch condition included in the setup.exe.

  For the other question, managed appliactions are not guaranteed to be compatible with other framework versions.  I am not familiar with this particular application however it appears to have been built with the 1.1.4322 Framework and will run against it.  I could not find any information stating that this application works with 2.0.50727 I believe you will have to download the 1.1 Framework to run it.

  Thank you for your help, Johan.
  
  Half my problem is now solved.
  
  The application now does indeed run with both versions of the framework when installed. Even if I force it to use version 2.0 with <requiredRuntime> it still performs great.
  
  The only remaining problem is the installer. It is most likely the setup.exe that is included in the setup build that requires version 1.1.
  
  This raises a new question.
  
  Can I just forget about the setup.exe and distribute only the msi package Or am I missing something important then
  
  again, thanks for your help. I am really an amateur in setup & deployment.
  
  Ruud.
