SYMPTOMS

Near the end of setup, the following error message may appear and the InstallShield setup may stop responding:

Unable to create the registry set: PreBuild Server

This problem only occurs when:

The computer on which setup is being performed has had a previous version of SQL Server installed.
The default registry permissions have changed.

CAUSE

Setup for SQL Server 7.0 detects that an earlier version of SQL Server has been installed and attempts to copy the registry keys that store the configuration information for the previous version. If the account you are using to install SQL Server 7.0 does not have the appropriate permissions on these registry keys, this error will be displayed.

WORKAROUND

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Log into Windows NT using the local Administrator account.
Run RegEdt32.exe.
Check the registry permissions on the following keys by highlighting the key in the left-hand pane and selecting Permissions from the Security drop-down menu:
HKEY_LOCAL_MACHINE\Software\Microsoft\MSSQLServer HKEY_LOCAL_MACHINE\Software\Microsoft\MSSQLServer\MSSQLServer

The Administrators local group should have Full Control on both keys. If it does not, grant the Full Control permission by clicking the Add button.
Reinstall SQL Server 7.0.
