  Hello All ,
  
  we have used spread .NET trial license While running a .NET application.
  
  While launching the application we face below error:

  Error Message: Exception of type ‘System.Web.HttpUnhandledException’ was thrown. System.Web.HttpUnhandledException (0x80004005): Exception of type ‘System.Web.HttpUnhandledException’ was thrown. —> System.ComponentModel.LicenseException: License for the Spread cannot be found.”

  One more thing, I have gone through the below forumn and observed the below key points that ,
  
  licenses.licx is present in properties under my project solution but I could not see the App_Licenses.dll in bin folder.
  
  I donno whether it comes in trial license or not

  Hello,

  Do you have License.licx file in your project with appropriate license string? If yes, then on License.licx file in your project, you may right click this license.licx and click on “build run time licenses”, it should create one App_Licenses.dll file in your project and then clean, rebuild and run your application.

  Let me know if this doesn’t help you.

  And if possible please send us a small sample replicating the issue so that we can investigate this issue further.

  Thanks,
  
  Reeva

  Hello Sudhanshu,

  Yours is a WebApplication or a Website? Because, for licensing Web Site applications, open the Visual Studio Build menu and select Build Runtime Licenses to create the App_Licenses.dll file works.

  Thanks,

  Hello Sudhanshu,

  Could you please clarify how long did you have this trial license? Is it still valid or expired?
  
  Further, I cannot see any Spread License entries in your Licenses.licx file, all entries are for devexpress items.

  However, if you have spread entries in Licenses.licx file then please clarify does the reference in your project have the same version as your Licenses.licx file? Does the licx file have a build action set to “Embedded Resource”?

  Please confirm.

  Thanks,
  
  Reeva
