System.IO.FileLoadException: 'Could not load file or assembly

Aspose.PDF Product Family
#1

Hai,
When I try to convert a pdf document to docx, following exception is being thrown
“System.IO.FileLoadException: ‘Could not load file or assembly ‘System.Security.Permissions, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The located assembly’s manifest definition does not match the assembly reference. (0x80131040)’”

I am using a licensed version of Aspose, I got this exception after upgraded Aspose words and pdf to latest version. It was working fine before
