I'm running IE8 on a 64-bit Vista machine. When I try to open a .pdf file in a browser, I receive the error message:
'The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again.'
I have Reader 9 and Acrobat from CS5 installed and fully operational. What do I need to do to view .pdf files in Internet Explorer 8?
