Hi there, My newly installed SSRS from the SQL Server 2008 Express stop working all of a sudden. When trying to start in SQL Server Configuration Manager, it gave me the error " The request failed or the service did not repond in a timely fashion. Consult the event log or other applicable error logs for details." Then from the log file in C:\Program Files\Microsoft SQL Server\MSRS10.SQLEXPRESS\Reporting Services\LogFiles\C:\Program Files\Microsoft SQL Server\MSRS10.SQLEXPRESS\Reporting Services\LogFiles\SQLDUMPER_ERRORLOG.logIt stated...(A20:A24) 12/21/08 11:26:28, ERROR , ReportingServicesService.exe, Unable to open file , error 3(A20:A24) 12/21/08 11:26:28, ERROR , ReportingServicesService.exe, Right instance-specific key can not be determinedCan someone help me please?Thank You.

Reinstall everything, now I am getting error installing ssrs, error: invalid class

I have the same problem since install. The reporting service would not start at the end of install. Other parts of the software work fine. - I tried to increase the service start timeout from registry to 60 sec, didn't solve the problem - I checked my Windows updates, didn't find problematic updates described in other posts Any idea ?

When the reported issue occurs, please use Start>Run>eventvwr to open and access the Windows Event Viewer. The Application log will have a corresponding event that will be logged. In one instance, it had an Event ID 59 with these details that helped solve the issue (For the reported issue, it could refer to C:\Program Files\Microsoft SQL Server\MSRS10.SQLEXPRESS\Reporting Services\ReportServer\bin\ReportingServicesService.exe.Config) - Log Name: Application Source: SideBySide Date: 5/12/2011 11:22:00 AM Event ID: 59 Task Category: None Level: Error Keywords: Classic User: N/A Computer: <Fully Qualified Name of the Reporting Services Server> Description: Activation context generation failed for "C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin\ReportingServicesService.exe".Error in manifest or policy file "C:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin\ReportingServicesService.exe.Config" on line 16.
