Error in client machine log4net when print crystal report...

[jmelendez-planas66]

Hello,

I made a c# program with VS 2019 with crystal report for visual studio. All works well in my machine.

I'm installing in my client with Clickonce. But I having a problem in my client with this error:

System.TypeInitializationException: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. --->
System.TypeInitializationException: The type initializer for 'CrystalDecisions.Shared.SharedUtils' threw an exception. ---> System.IO.FileLoadException:

For the file log4net, I changed the publish Status in the Application Files to "Include" but I still have the same error.

Then I installed the log4net NuGet Package in my application, remade the clickonce setup, and I still have the same error.

When I look in the my client machine, I see that file where clickonce install the application.

Any idea to fix that issue?

The error typically means it can't find the Crystal viewer herre:

C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319

Add the folder to your project then it will work.

Don't include the 2.0 version, IIS will load both and that will cause a problem.
