Your application is referencing version 1.2.13.0 of Log4Net. However, the Crystal .NET SDK uses version 2.0.12.0. You need to upgrade the version of Log4Net that your application is using so that it matches what the SDK requires.

Yes, How can I upgrade Log4Net version?

[DellSC · Accepted solution]

1. Do a search on your drive(s) for log4net.dll. Check to see whether any of the files that are found are version 2.0.12.

2. If you don't have the correct version get it from the NuGet repository. This will install it so that VS can use it.

3. Remove the old version from the References for your project and add the new version.
