We recently have noticed some issues with Aspose.Pdf for .NET 4.9.0 when loading the license file in .NET Framework 4.0. However, in order to test the particular scenario that you are experiencing, please share the license file. Please visit the following link for information on How to send a license?
I have tested the scenario and I am able to notice the same problem. As I have shared earlier, the problem is already logged as PDFNET-23909 in our issue tracking system. Our development team is looking into the details of this problem and soon you will be updated with the status of correction. Please be patient and spare us little time. We apologize for your inconvenience.
It happens to me as well, PDF is completely broken at this point. To be specific, it throws several errors, but I cannot License this product at all. Is there a work around? We just purchased this product, and cannot move forward with our development.
We already have been able to figure out the reasons of this problem and respective correction has been made to the product. The hotfix will be provided, shortly.
Please be patient and spare us little time. Your patience and comprehension is greatly appreciated in this regard. We are really sorry for your inconvenience.
