I must install .Net 1.1 on Windows 7, so I am using this procedure (which is also the procedure recommended by Dell).

Problem: When I ran dotnetfxsp1.exe /Xp:C:\DotNet\netfxsp.msp nothing happened, and in particular no file was created in C:\DotNet. And the next command msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp failed with this message:

This patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package

What did I do wrong?

I am on Windows 7 Enterprise 32 bit, and this is the content of my C:\DotNet folder:

enter image description here


Running these two commands a second time, the error did not occur again:

dotnetfxsp1.exe /Xp:C:\DotNet\netfxsp.msp
msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp

The first one does not make any dialog appear, only a spinner appears. The second command makes a progress dialog appear and then disappear within seconds with no error message.

Now just run the generated netfx.msi installer.
