Could not load file or assembly 'Telerik.Reporting' on IIS without any references in the project to it

Question

I have a web site on IIS. There are a lot of virtual folders with separates sites on it.

I`ve updated one of them and got "Could not load file or assembly 'Telerik.Reporting, Version=6.2.13.110, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' or one of its dependencies. The system cannot find the file specified."

The same errors on the other virtual folder`s sites.

Stack Trace.`[FileNotFoundException: Could not load file or assembly 'Telerik.Reporting, Version=6.2.13.110, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' or one of its dependencies. The system cannot find the file specified.] System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks) +0 System.Reflection.RuntimeAssembly.InternalLoadAssemblyName(AssemblyName assemblyRef, Evidence assemblySecurity, RuntimeAssembly reqAssembly, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks) +210 System.Reflection.RuntimeAssembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean forIntrospection) +242 System.Reflection.RuntimeAssembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) +17 System.Reflection.Assembly.Load(String assemblyString) +35 System.Web.Configuration.CompilationSection.LoadAssemblyHelper(String assemblyName, Boolean starDirective) +122

But in this project I don`t use Telerik at all. I created new site on IIS, deploy this project and one work well. But in the main one I still get the error.

What should I do to remove this issue from site with virtual folders? I have to deploy this project to it. I can`t delete it and create new one.

Any suggestions? Restart doesn`t help.

There could be other Web.configs that reference the telerik assembly. You would need to check all of them
