Build .NET Framework 4.8 for legacy operation systems (Windows XP, Vista)

1. Visit abbodi1406/dotNetFx4xW7 repository on GitHub.

2. Click on the green button < > Code and click on download ZIP.

3. Download official .Net Framework 4.8 from Microsoft.

4. Extract the ZIP file you downloaded in step 2.

5. Move the .Net Framework installer into the main extracted folder, it will be like that:

   

6. Run dotNetFx.cmd as administrator and wait until it finishes processing the installer.

7. Run 7zSFX.cmd as administrator to recreate the modified installer.

9. Copy the new file to your real\virtual machine and setup it

10. Restart the target Windows (on which, WinPaletter will work)

11. In Windows Vista, when you run WinPaletter you might face a KERNEL32.DLL error. If so, download a modified CLR.dll from either Framework or Framework64 folder from this link and then copy CLR.dll to %windir%\Microsoft.NET\Framework\v4.0.30319\Framework or %windir%\Microsoft.NET\Framework\v4.0.30319\Framework64 and replace. If you found both Framework and Framework64, then you will download two CLR.dlls and move them to their corresponding folders, and finally restart the target Windows.
