Customer upgraded their systems to Windows 7 and Acrobat 11.0. We are having problem with e-signing through  our application. E-signing works out of box to e-sign a pdf but it is not working with our system. Previously System had Acrobat 9.0 and it was working for e-signing. Basically we are using customized JavaScript in our application that works for e-signing. It was working for Acrobat 9.0 when we were placing it in installation folder of Acrobat 9.0. It is not working for Acrobat 11.0. Error that we are getting is  “-2146827850 Object doesn’t support this property or method.”
