- Did you try our latest version of the Showcase project here
- If yes, provide us sample code, how you apply license
- Did you clear cache/temp folder before running application, sometime it shows cached files
Thank you for giving a try to GroupDocs.Annotation for .NET API.
We are sorry to hear that you are facing such issues. Kindly click here to view the trial limitations for using GroupDocs.Annotation for .NET API. I have verified all others sample files available in showcase example project and found that API is working fine with other files as well after applying license . From your screenshot i can assume either your license is not properly set or your trial period for temp license is expired, please confirm these scenarios as well.
kindly have look here for setting license file path. Also here is the image from where you can see the difference after applying license file "trial limitation batch is not appearing ".
Hope this will resolve your issues.
