Valid digital signatures in Windows XP are no longer valid in Windows 7

Apr 20, 2012 2:49 PM

We have a Windows application that uses axAcroPDF control to display digitally signed and validated forms. The PDF document was displayed correctly (Signed and all signatures are valid ) in Windows XP environment. However, recently our organization switched to Windows 7 machines. The digitally signed PDF documents no longer has valid signatures message. Instead the message "The certification/signature is still being validated" is displayed and it does not get validated. There is an exception "AcroRd32.exe:Access violation reading location 0x00000042"

Could someone help me to resolve this issue?

Thanks!

    Moving this discussion to the Security & Digital Signatures forum.

    What is the ‘axAcroPDF’ control? What version of Reader?

    Ok. I think I understand you are using the Acrobat SDK. If that's true, you need to go to an SDK/developer forum.
