Downloadable versions of Aspose.OCR and Aspose.OMR had sever performance issues and were not meeting the customers’ expectations. Development process is slower because of such issues and you see less new features/fixes in the process.
Aspose.Cloud servers have enough resources to overcome such performance issues and we are targeting those servers for further development. Downloadable version of Aspose.OCR will not be able to meet customers’ expectations in the near future and it is expected to be discontinued soon. We recommend migrating to cloud version of Aspose.OCR and Aspose.OMR to get better performance and get quick fixes to your issues.
As far as the download link to template editor is concerned, you can download an older version of Aspose.OCR from Nuget (https://www.nuget.org/packages/Aspose.OCR/) and use template editor from that version.
We are sorry for the inconvenience.
