  In Windows 8.1, while installing ClonaDesk it gives the message as “This application requires one of the following versions of .Net Framework: .Net Framework, Version=v4.5.2 Do you want to install this .Net Framework version now?”

• Answer

  If you have already installed the .NET Framework 4.5.2 on your Windows 8.1 computer but are still encountering issues where your application asks you to install it, there are a few steps you can take to troubleshoot and resolve this issue:

  1. Verify .NET Framework Installation:
     • Go to "Control Panel" > "Programs" > "Programs and Features."
     • Check if Microsoft .NET Framework 4.5.2 is listed in the installed programs. If it's there, it means the framework is installed.
  2. Repair .NET Framework Installation:
     • If you find .NET Framework 4.5.2 listed, you can try repairing it to ensure it's functioning correctly. Right-click on it and select "Change" or "Repair," then follow the on-screen instructions.
  3. Check Registry Entries:
     • Sometimes, issues with .NET Framework can be related to incorrect registry entries. Be cautious when editing the registry, as it can cause system instability if not done correctly.
     • Press Win + R, type "regedit," and press Enter to open the Registry Editor.
     • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full in the registry.
     • Check if the Version DWORD value is set to 4.5.51209. If not, you can try modifying it. Right-click on Version and select "Modify." Enter 4.5.51209 as the value data.
  4. Windows Update:
     • Make sure your Windows 8.1 is fully up to date. Sometimes, Windows updates can resolve issues related to the .NET Framework.
  5. Check Application Configuration:
     • Ensure that your application is configured to target the correct version of the .NET Framework (in this case, 4.5.2). Verify the application's app.config or web.config file if applicable.
  6. Reboot Your Computer:
     • Sometimes, a simple system restart can resolve issues related to .NET Framework.
  7. Use .NET Framework Repair Tool:
     • Microsoft provides a .NET Framework Repair Tool that can help diagnose and repair issues with the framework. You can download and run this tool from the official Microsoft website.
  8. Reinstall .NET Framework:
     • As a last resort, you can try uninstalling .NET Framework 4.5.2 and then reinstalling it. Make sure to download the installer from the official Microsoft website.

If you've tried all of these steps and are still facing issues, it might be a good idea to contact the support or forums for the specific application you're trying to run. They may have additional insights or solutions specific to their software.
