Don't know exactly what your problem is but I see similar posts to the MS News groups about SQL 2K install problems.
and this is typically the comments the MS engineers make, heres a set of steps from one of them
Please try these steps:
1). Delete all SQL Server related registry key:
HKLM\Software\Microsoft\MSSQLServer
HKLM\System\CurrentControlSet\Services\MSSQLServer
HKLM\System\CurrentControlSet\Services\SQLServerAgent
Sometimes you need to delete this key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Setup\ExceptionComponents
2). Reinstall the SQL Server.
Or,
3). Try x86\setup\setupsql.exe k=dbg to setup SQL Server in debug mode.
At the very least, step 3 will produce a detailed log you can post to MS and maybe they can help.
Also, I suggest if you get really stuck your try the MS SQL Server Setup nesgroup on msnews.microsoft.com
[need a news client to read/post there - outlook is the usual one most folks use].
