@edward_stod227 probably because your version of Windows 7 does not contain the necessary function that the newer version of Adobe Acrobat Reader is trying to use. Once Acrobat tries to load a modern feature that Windows 7 simply doesn't support, that's win you get the error message

That page says nothing about Win7 nor is there a link to the correct file needed to add the missing link. Please offer some better help to us poor Win7 users.
