.NET Framework 1.1 Installation Error

Need to install an old program that requires .NET Framework 1.1 today. However, my 64-bit Windows 7 give errors before installation could complete.

As usual, ask Mr Google bout the problem and found this helpful website.

If the command generate error "dotnetfx.exe" is not recognized as an internal or external command,
operable program or batch file; this means that the computer could not find the file specified. Make sure that the file NDP1.1sp1-KB867460-X86.exe is renamed and saved as dotnetfxsp1.exe

By adding

C:\Dotnet\ before;

• dotnetfx.exe /c:"msiexec.exe /a netfx.msi TARGETDIR=C:\DotNet" and
• dotnetfxsp1.exe /Xp:C:\DotNet\netfxsp.msp
• msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp
• Run netfx.msi

as suggested by a user in microsoft website could solve the problem. 

Happy installing ~
