32-bit SQL Server failover clustering is not supported on 64-bit versions of Windows
A 32-bit installation of Microsoft SQL Server failover clustering is not supported on 64-bit versions of Windows. However, the Setup for Microsoft SQL Server 2005 or for Microsoft SQL Server 2008 may let you install 32-bit failover clustering for the SQL Server Engine and for SQL Server Analysis Services on a 64-bit version of Windows.
Note This issue does not occur in the following versions of SQL Server. In these versions, Setup blocks the installation of 32-bit Microsoft SQL Server failover clustering on 64-bit versions of Windows:
- Microsoft SQL Server 2008 Cumulative Update 2
- Microsoft SQL Server 2008 R2
- Microsoft SQL Server 2012

If you run the BPA tool and encounter an Error that has the title of Setup -WOW64 not supported for SQL Failover Clustering, then your 32-bit SQL Server 2008 or SQL Server 2008 R2 installation is installed in this unsupported configuration. | SQL Server 2008

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
