Unable to install SQL Server CE Server Tool on SQL Server 2000 SP 4

Hi
I am facing problem with installing SQL Server CE Server Tool,

I have installed SQL Server 2000 SP 4 which is working fine.

While i am running Setup of "SQL Server 2000 Windows CE Edition version 2.0" ,Developer tools installed successfully but incase of SQL Server CE Server Tool i am getting following Error
"SQL Server CE Tool is compatible only with SQL Server 2000 Service pack 1 and higher.
When you install SQL Server CE Server Tools on a computer running both IIS and SQL Server 2000 , ensure the installer for SQL Server CE Server Tools corresponds To the version of SQL Server 2000."

I am sure that i have running SQL Server 2000 SP 4 (MSDE also SP 4) , IIS (Version 5.1) is also working fine , and one more thing i am trying to install SQL Server CE Server Tool setup is "sqlce20sql2ksp4.exe" (Which i downloaded from microsoft site.).Here all the requirement is fulfill but i dont know what is going to wrong.

I wasted my 2 days behind solving this issue , now i am tiered ,So please any one have solution for this issue.
Help me please.

Thanks in advance.
