IIS8 64-bit app pool - Arithmetic overflow

[jslots]

Dear e-Iceblue,

Currently we are using your Spire.NET libraries to generate PDF documents. Within IIS7.5 on a WinServer 2008R2 it works just perfectly, we are however migrating to IIS8.5 on WinServer 2012R2.

When our software runs in a 64-bit app pool (the default settings) we're unable to generate PDF documents (if the app pool is set to 32-bit everything works like a charm though). As it has our preference to run everything 64-bit, the following question arises.

What version (if any) supports 64-bit app pools in IIS8.5 on WinServer 2012R2?

Below you'll find the stack trace we encounter.

Stack trace:

System.OverflowException: Arithmetic operation resulted in an overflow.
at System.IntPtr.ToInt32()
at Spire.Pdf.Graphics.PdfBitmap.5()
at Spire.Pdf.Graphics.PdfBitmap.2()
at Spire.Pdf.Graphics.PdfBitmap.Save()
at Spire.Pdf.Graphics.PdfBitmap.4()
at Spire.Pdf.Graphics.PdfBitmap.Save()
at Spire.Pdf.Graphics.PdfCanvas.DrawImage(PdfImage image, Single x, Single y, Single width, Single height)

Thanks in advance.

Hello,

Thanks for your inquiry.
Sorry that we don't have the version you mentioned.
Because in our product some methods call the 32-bit functions.

Hello Sweety,

Thank you for the quick reply.

Ok, we will then continue to run our product within a 32-bit app pool.
