Report Builder of SQL Server 2008 R2 Service Pack 3 does not launch.

Dear Customers

we have discovered a problem with Report Builder that ships with SQL Server 2008 R2 Service Pack 3.

If you installed SQL Server 2008 R2, have upgraded it to Service Pack 2 and then applied Service Pack 3, then Report Builder will fail to launch. It will raise the following error.

 ERROR SUMMARY

Below is a summary of the errors,
details of these errors are listed later in the log.

* Activation of https://.../ReportServer/ReportBuilder/ReportBuilder_3_0_0_0.application resulted in exception. Following failure messages were detected:

+ File,
Microsoft.ReportingServices.ComponentLibrary.Controls.dll, has a different computed hash than specified in manifest.

We are not planning to release a fix for this issue. Instead we recommend you implement one of the following workarounds.

• Client side workaround:
  • Install and run Report Builder 3.0 of SQL Server 2008 R2 RTM from the following location: https://www.microsoft.com/en-pk/download/details.aspx?id=6116

• Server side workaround:
  • Uninstall Service Pack 3 then uninstall Service Pack 2 and then reinstall Service Pack 3.

We acknowledge the inconvenience. Apologies for this.

• Updating the SQL Server Release Services Blog post announcing the release of SQL Server 2008 R2 Service Pack 3 to add a note to proactively inform customers.
• Updating the download page of SQL Server 2008 R2 Service Pack 3 to add a note to proactively inform customers.
