Microsoft distributes Microsoft SQL Server 2012 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2012 fix release.
Symptoms
When you perform an unattached installation to add 32-bit Microsoft SQL Server 2012 Reporting Services (SSRS 2012) by using a configuration file, the installation fails, and you receive the following error message:
Operation Failed with Error 0x8007000B
An attempt was made to load a program with an incorrect format.
This issue occurs when the following conditions are true:
-
You perform the unattached installation on a computer that is running Windows Server 2008 R2.
-
The computer has the Windows Communication Foundation (WCF) activation feature installed.
Cause
This issue occurs because the Aspnet_regiis -ir command cannot run from the 32-bit Microsoft .NET Framework directory on a 64-bit Windows Server 2008 R2-based computer.
