Telerik® JustTrace™ by Progress



Slowing down of or inability to start your web sites, services or .NET applications

If JustTrace is terminated unexpectedly some registry keys which are required for the profiling process may remain set. In this case the core profiler of JustTrace will be trying to profile them. To remove the profiling settings start the CleanRegistryKeys_x64.reg or CleanRegistryKeys_x32.reg (depending on your OS version). It is located in JustTrace's install directory, which is usually C:\Program Files (x86)\Telerik\JustTrace.

Live data is not showing values for some of the .NET performance counters

You may need to re-register the counters. Start an administrator command prompt and execute the following commands:

For Windows 7

unlodctr .NETFramework

lodctr /r

lodctr %WINDIR%\Microsoft.NET\Framework\<Framework_ver>\CORPerfMonSymbols.ini , where <Framework_ver> is the directory of the .NET Framework version which contains the CORPerfMonSymbols.ini file. It should be either or if 4.0 is not installed.

For Windows 8 and .NET 4.5

unlodctr .NETFramework

lodctr /r

lodctr %WINDIR%\Inf\.NETFramework\CORPerfMonSymbols.ini

The profiler session doesn't start and displays the "Waiting for response from the profiled application" dialog after a Silverlight application has started successfully You are using a browser that is not fully supported. Stop the session, close all browser instances and restart profiling. Alternatively, use one of the well-supported browsers listed in Silverlight.

Missing Visual Studio extension or JustTrace menu after successful installation

Try the following:

  1. Open Visual Studio, go to TOOLS -> Extensions and Updates....
  2. If JustTrace is in the list of installed extensions, uninstall it from there.
  3. Go to the extensions folder of Visual Studio:

    • default location for Visual Studio 2013: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions or C:\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\Extensions
    • default location for Visual Studio 2012: C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions or C:\Program Files\Microsoft Visual Studio 11.0\Common7\IDE\Extensions
    • default location for Visual Studio 2010: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ExtensionsorC:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions
  4. Delete all folders that have Telerik.JustTrace.* DLLs in them (the name of the folders should follow pattern like this "4uus3xan.ur4")
  5. Run Notepad as an Administrator.
  6. Go to File -> Open and navigate to C:\Program Files (x86)\Microsoft Visual Studio <10.0, 11.0 or 12.0>\Common7\IDE\Extensions
  7. Change the file types to "All Files".
  8. Open extensions.configurationchanged file and save it without changing anything in it(File -> Save). This will refresh the list of extensions that Visual Studio uses.
  9. Go to the JustTrace install folder (default is: C:\Program Files (x86)\Telerik\JustTrace\Libraries).
  10. Run Telerik.JustTrace.VS.vsix as administrator and proceed with the manual installation of the extension.
  11. Check if the missing JustTrace extension/menu is fixed afterwards.
  12. If the above does not solve the issue, it is likely that you need to repair Visual Studio:

    • Go to Uninstall a Program from the Windows Control Panel.
    • Right click on Microsoft Visual Studio 2010/2012/2013 and select Uninstall/Change.
    • Select Repair/Reinstall from the options.
