getting MSDE installed so ASP.Net Matrix will see it

My first try was:
Setup.exe /qb+ INSTANCENAME=VSDOTNET DISABLENETWORKPROTOCOLS=1 SAPWD=matrixsa

After reading all of this
http://www.asp.net/Forums/ShowPost.aspx?tabindex=1&PostID=221310
I removed msde via the control panel and reinstalled it using (I think)

Setup.exe BLANKSAPWD=1

I still don't have a working MSDE that shows in the taskbar.
Its in Sevices and I have started it.
But I can't connect with ASP.Net Matrix.

There are 9 pages on instructions here

Customizing Desktop Engine Setup.exe

Can someone please give me the receipe that will work?I got it to work.
Somewhere I found which registry key to delete.
Then I used the setup.ini instead of the command line.
After that I started the service of the named instance of SQLServer specified in the
setup.ini file.
Next I attempted to setup one of the sample programs.
It got to the point where I could verify the connectablility to the database and then complete the installation.

At this point I got a message that it could not find C:\Inetpub\Wwwroot so the install did not complete.

I had already installed the IIS componet but it did not create C:\Inetpub\Wwwroot so I created these folders myself.

Next I installed the Reporting sample and installed all the way and worked!

After that I went back to the control panel to repair the first sample application.
It did not fix the problem of some missing JavaScripts.
The message said to run aspnet_regiis.exe -c.
This did not work with the Star/Run so I opend a command prompt and navigated to
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322 and here I entered aspnet_regiis.exe -c
which created the missing javascripts so now the first sample application does work!

Well I hope this detail helps someone else.
