Microsoft .NET Framework 1.1 installation problem on Windows Vista

Today I met one problem when trying to install Microsoft .NET Framework 1.1 under Vista SP1 32bit. Luckily Google told me the answer again.

We need to slipstream .NET 1.1 SP1 into .NET Framework setup package to have a integrated .NET Framework 1.1 SP1 installer.

From the link:

1. Create a new folder named DotNet in C:\ drive (C:\DotNet is used in this guide, you can change to any folder you prefer, but ensure that you use correct path in the following steps).

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). Make sure that the file is renamed and saved as dotnetfxsp1.exe, so that the rest of the steps can be followed easily.

4. Move both installation files into the same directory (i.e. C:\DotNet), if you’re not saving them together.

5. Open command prompt as Administrator.

6. Change to the directory where the two installation setup files for .NET 1.1 are saved (i.e. C:\DotNet).

7. Run the following commands one by one, press Enter after each one.
* dotnetfx.exe /c:"msiexec.exe /a netfx.msi TARGETDIR=C:\DotNet"

* dotnetfxsp1.exe /Xp:C:\DotNet\netfxsp.msp

No status message for this step.
* msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp
Wait for Windows Installer for Microsoft .NET Framework 1.1 to finish and disappear automatically.

8. Install Microsoft .Net Framework 1.1 with slipstreamed/integrated Service Pack 1 by running netfx.msi created in the working folder.
