How to install .Net 1.1 on windows 7

To install .net 1.1 on windows 7 follow these steps:

1. Create a new folder named DotNet in C:\ drive. (The path i used was C:\DotNet )
2. Download Microsoft .NET Framework 1.1 Redistributable Package (dotnetfx.exe). Make
sure the setup file is saved as dotnetfx.exe.
3. Download Microsoft .NET Framework 1.1 Service Pack 1 (NDP1.1sp1-KB867460-
X86.exe). Rename the file to dotnetfxsp1.exe.
4. Copy both installation files into the same directory (i.e. C:\DotNet),.
5. Open Command Prompt as Administrator.
6. Change to the directory where the two installation files are stored, ie C:\DotNet.
7. Run the following commands one by one.

--> dotnetfx.exe /c:"msiexec.exe /a netfx.msi TARGETDIR=C:\DotNet"

Click on Yes and wait for this dialog which says installation complete.

--> dotnetfxsp1.exe /Xp:C:\DotNet\netfxsp.msp

--> msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp

Wait for the installer to disappear automatically.

8. Install Microsoft .Net Framework 1.1 with slipstreamed Service Pack 1 by running netfx.msi from the working folder.

Dotnet Framework 1.1 is successfully installed. :-)
