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.

    This looks really promising. I'll investigate any knock on effects of enabling 32bit mode on existing sites in IIS. – reticentKoala Oct 31 '12 at 11:40
