Application not working

[grahamlabdon]

Hi Gurus

I have an application that is throwing an exception when the main form is created.

Application.Run(new frmMain());

This throws the following exception -

System.IO.FileNotFoundException was unhandled
  Message="The specified module could not be found. (Exception from HRESULT: 0x8007007E)"
  Source="ConfigurationTool"
  StackTrace:
       at ConfigurationTool.frmMain..ctor()
       at ConfigurationTool.frmMain.Main() in C:\NGC\source\Configuration Tool\ConfigurationTool\frmMain.cs:line 490
       at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args)
       at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args)
       at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly()
       at System.Threading.ThreadHelper.ThreadStart_Context(Object state)
       at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
       at System.Threading.ThreadHelper.ThreadStart()

Does anyone have any idea what is going on?

Thanks in advance

Graham

Check frmMain.cs:line 490

Did you delete ApplicationName.exe.config?

It looks like an assembly is missing, or the framework is corrupted, or some security policy prevents the application from running... There are tons of possible reasons.

You should provide more details, at least what file is missing.\

You could try to use fuslogvw.exe to check the log of assembly resolution failures. (It is part of SDK and should reside somewhere in VisualStudio installation directory).

Also check the konstructor of frmMain, if any file operation is performed here.
