Issues With Microsoft SQL Serever 2005 Express Edition And Other Versions Of SQL Express

I have uninstalled the SQL Server Express Edition that I have installed from the CDs that were given to me during a Chicago Conference when READY TO  LAUNCH Visual Studio 2005, SQL SERVER 2005, and Biz Talk 2005.
Then I went to microsoft website: http://msdn.microsoft.com/vstudio/express/sql/register/default.aspx and downloaded and installed the so called Microsoft SQL Server 2005 Express Edition and I got the messages Error that you read below. Then I Uninstalled Microsoft SQL Server 2005 Express Edition  and went again to msdn website and downloaded Microsoft SQL Server 2005 Express Edition Advanced Services SP1 and installed it. I got again the same message as below.
 
MESSAGE:
 
1. First comes a window with the title: €œsetup.exe €“ Unable to Locate Component€?
And it displays a message:
This application has failed to start because MSTDCPRX.dll was not found.
Re-installing the application may fix this problem.
2. After I click the OK button of this window it comes another window with the title: €œMicrosoft SQL Server 2005 Server Setup€?
And it displays a message: Failed to load SqlSpars.dll
 
 
Does anybody can tell what is going on with the 3 times I tried to installed different SQL Server 2005 Express Edition and I get the same message?????
 
Thanks for your help and support when you have time to respond.
Sincerely,
TonyC
