    Valid digital signatures in Windows XP are no longer valid in Windows 7

    Swat_mpg Community Member

      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?
