Error:

 

Installating DEFAULT instance of SQL Server 2008 R2 Express Edition with Advanced Services on a Windows 7 64bit with AMD Phenom(tm) II X4 945 Processor failed with error:

Rule Check Result 

--------------------------- 

Rule "Same architecture installation" failed.

 

The CPU architecture of installing feature(s) is different than the instance specified. To continue, add features to this instance with the same architecture.  

--------------------------- 

OK

Root Cause:

 

Uninstallation of DEFAULT instance of SQL Server 2005 64-bit Developer edition was not clean and I was able to see instance MSSQLSERVER mapped to MSSQL.2 in the registry. After cleaning up the registry, rule "Same architecture installation" succeeded.
