Problem: When opening the Znode solution with Visual Studio, a migration report with an error is presented.
Solution: Install SSRS if desired. Note that Znode currently has reports implemented in two different frameworks: (1) SSRS, and (2) DevExpress. The DevExpress reports are replacing the SSRS reports, so SSRS reports are not critical to have functional.
Bottom line: This error can be safely ignored if not interested in Znode's deprecated SSRS reports.
