Error: "Unable to start reports viewer application. Configuration system failed to initialize" (4236066)

When using the Online Restore Wizard, when you attempt to geneate a comparision report the following error message is shown:

"Unable to start reports viewer application. Configuration system failed to initialize"

1. If you are using RMAD 8.5.2 or earlier, open the following folder on the RMAD server:
   <installDrive>:\Program Files\Quest Software\Recovery Manager for Active Directory\RMADReports\BRReportsViewer
2. If you are using RMAD 8.6 or later, open the following folder on the RMAD Server:
   <installDrive>:\Program Files\Dell\Recovery Manager for Active Directory\RMADReports\BRReportsViewer
3. Rename BRReportsViewer.exe.config to BRReportsViewer.exe.config.old
4. Try running a report again

If after renaming the config file you get an error similar to the following, you will need to check if there is corruption with the .NET 3.5 installation:

"Unable to start reports viewer application. The configuration section 'connectionStrings' has an unexpected declaration"

1. Open regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5
2. Confirm the following values exist:
    - Version = 3.5.30729.5420
    - Install = dword:00000001
    - InstallPath = C:\\Windows\\Microsoft.NET\\Framework64\\v3.5\\
3. Open the following folder C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG\
4. Confirm the machine.config file exists
5. Open the machine.config file and confirm the following XML code exists under the configuration/configSections node:
   <section name="connectionStrings" type="System.Configuration.ConnectionStringsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" requirePermission="false"/>

If any of the registry values are missing, or if there are issues with the machine.config file, you may need to reinstall .NET 3.5. Try running the .NET repair tool to see if it can repair any issues: http://support.microsoft.com/kb/2698555
