This Article Applies to all versions of Reports Center Standard & Professional.
Causes & Solutions:
1. Existing installations of WebAdvantage with SSL enabled before installation or other applications having created SSL certs.
Basically, if a default Web site is created within Microsoft Internet Information Services (IIS) a generic SSL certificate this is generated by windows. This certificate will have to be removed before the installation of the Reports Center Standard & Professional can finish, this is due to the fact that the Reporting Services portion of the installation will not continue with a pre-existing SSL already preconfigured. This cert can be removed temporarily and added later once again. (Ref: WebAdvantage – Enabling HTTPS-SSL access (2003, 2008-Vista-7).pdf)
Solution: Remove the existing Default Web Site's SSL Server Certificate.
