SYMPTOMS
Consider the following scenario:
 * On a 64-bit operating system, you have the 64-bit version of Microsoft SQL Server 2005 installed.
 * You have the 64-bit version of SQL Server 2005 Service Pack 2 (SP2) installed.
 * You are trying to install the Windows on Windows (WOW) version of SQL Server 2005.

In this scenario, you receive the following error message during the installation of the 32-bit SQL Server 2005 Database Engine:

Windows Installer has stopped working

<div class="cause_section">

CAUSE
This problem occurs because a shared file between the 32-bit version and the 64-bit version of SQL Server 2005 is not updated appropriately.

<div class="workaround_section">

WORKAROUND
To work around this problem, install the 32-bit version of SQL Server 2005 SP2 before you install the WOW version of SQL Server 2005.
