Fxcop.exe – .NET Framework Initialization Error

Asked By 790 points N/A Posted on -

FxCop is an application that analyzes the assemblies of managed code (code that directs the .NET Framework common language runtime) and information about the assemblies, such as potential design improvements, localization, performance, and security.

For two days, I am getting this error while trying to run fxcop.exe.

The screenshot of the error is

Unable to find a version of the runtime to run this application

Fxcop.exe – .NET Framework Initialization Error

Unable to find a version of the runtime to run this application.

I'm not sure about the cause as no ran with frequency. Last I used it while working on a project for a month. Now I need to re-run it, but now I'm getting the error mentioned.

I am using Windows XP SP2, visual studio 2008 and .net framework 4.0 . The hardware in my PC  is Core i3 processor with 2 GB of ram.

This error has many reasons to be raised. But all of them are related to the installation of .net framework. To overcome this problem, you have to repair the .net framework used. To do this, you can download the .net framework necessary and appropriate depending on the version of Visual Studio (I. e. Visual studio 2005, visual studio 2008 or visual 2010).

In the problem description, you mentioned that you use the .net framework 4.0, so you have to download .net framework 4.0.

The following steps are because you tried to fix the same mistake before. But if it doesn't work with you, trying to inform us once again.

  1. Download the .NET Framework cleanup tool cleanup tool and decides to clean the .NET Framework version that is causing problems in your system.
  2. Download and install the .NET Framework version that cleanse in step 1 (i.e., .NET Framework 1.1 or NET Framework 2.0). In your case (.Net framework 4.0).
  3. (Optional) Download and run the .NET Framework verification tool verification tool to verify that all .NET Framework files are installed correctly.
  4. Download and install the .NET Framework service desired (for example, .NET Framework 4.0 SP3) pack running the installation package directly instead of using Windows Update. Run it directly will enable the installation of the service pack display error dialog boxes instead of having them turn off Windows Update.

I hope that it helps you.
