Installing 32bit SSRS on 64bit Windows/IIS I've inherited a situation where I have SQL Server 2005 Standard 32bit running on Windows Server 2008 R2 64bit.

When I come to install SSRS components I'm warned that "Failed to find the ASP.Net Version Registration with Microsoft Internet Information Services (IIS)."

In IIS 7 and above, each application pool can run in 32bit mode. If I change all application pools into 32bit mode will this solve the problem?

Are the better alternative solutions?

Thanks in advance.
