How to install .NET Framework 1.1 on Windows 8.1

After update from Windows 8.0 to Windows 8.1 I found that .NET Framework 1.1 was unexpectedly disappeared. Here I give you the tested way to return it back:

  • Download .NET Framework Cleanup Tool (product guide here) from following locations: here or here
  • Unzip and run following commands:
    cleanup_tool.exe /q:a /c:"cleanup.exe /p .NET Framework 1.0"
    cleanup_tool.exe /q:a /c:"cleanup.exe /p .NET Framework 1.1"
  • Following instructions were taken from here:
    • Create a new folder named DotNet in C:\ drive. (The path i used was C:\DotNet)
    • Download Microsoft .NET Framework 1.1 Redistributable Package (dotnetfx.exe). Make sure the setup file is saved as dotnetfx.exe.
    • Download Microsoft .NET Framework 1.1 Service Pack 1 (NDP1.1sp1-KB867460-X86.exe). Rename the file to dotnetfxsp1.exe.
    • Copy both installation files into the same directory (i.e. C:\DotNet),.
    • Open Command Prompt as Administrator.
    • Change to the directory where the two installation files are stored, ie C:\DotNet.
    • Run the following commands one by one:
      dotnetfx.exe /c:"msiexec.exe /a netfx.msi TARGETDIR=C:\DotNet"
      dotnetfxsp1.exe /Xp:C:\DotNet\netfxsp.msp
      msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp
    • Install Microsoft .Net Framework 1.1 with slipstreamed Service Pack 1 by running netfx.msi from the working folder.

Good luck!
