If I run locally it works on Windows but just simple example with text hello world and it crashes always on document.Save
Unhandled exception. System.ArgumentNullException: Value cannot be null. (Parameter 'key')
Instructions for running C# Examples for Aspose PDF.Net seemed simple enough, but when I try to run one of the examples from VS2013, I immediately get 'access denied' against the 'Aspose.Pdf.Examples.CSharp.exe'. I have added various local Windows 7 accounts, i.e. NETWORK and LOCAL service, etc, along the directory path, and made sure it's 'full control', but get this error as soon as I try to run. Any help appreciated.

I want to add multiple signatures on a single Pdf. My code as follows `System.Drawing.Rectangle rect = new System.Drawing.Rectangle(100, 100, 100, 100);
PKCS1 signature = new PKCS1(@"eamsT.sinopec.com.pfx", "20180201");
PdfFileSignature pdfSign = new PdfFileSignature(new Document(@"input.pdf"));
pdfSign.SignatureAppearance = "test.png";
pdfSign.Sign(1, "Signature Reason", "Contact", "Location", true, rect, signature);
pdfSign.Save(@"output.pdf");
pdfSign.Close();
rect = new System.Drawing.Rectangle(260, 260, 100, 100);
PKCS1 signature2 = new PKCS1(@"eamsT.sinopec.com.pfx", "20180201");
pdfSign = new PdfFileSignature(new Document(@"output.pdf"));
pdfSign.SignatureAppearance = "test.png";
pdfSign.Sign(1, " Reason2", "Contact", "Location", true, rect, signature2);
pdfSign.Save(@"output.pdf");
pdfSign.Close();`
There is a problem that my reader (Adobe Acrobat Reader DC)tells me that Signature verification statusThe signature is invalid.The document has been altered or corrupted since the signature was applied.
I am running into a NullReferenceException using Aspose.PDF 19.4 in my own application and narrowed it down to the Save method on a Document. To make sure it wasn't my code causing the issue, I tried running the hello world example in this repo but tweaked to save to a stream to match how my app was working, and got the below error. Any ideas how to fix this?
// Initialize document object
Document document = new Document();
// Add page
Page page = document.Pages.Add();
// Add text to new page
page.Paragraphs.Add(new Aspose.Pdf.Text.TextFragment("Hello World!"));
// Save updated PDF
using (var stream = new MemoryStream())
{
document.Save(stream);
}
// ExEnd:1 System.NullReferenceException: Object reference not set to an instance of an object
