Fix Adobe’s broken PDF preview in x64 Windows

Adobe’s PDF previewer control doesn’t work correctly in x64 Windows because the Adobe Acrobat installer has a bug since June 2007. To be clear, the PDF preview handler works fine on x64 Windows but the Adobe Acrobat Reader setup program doesn’t install it correctly.

This affects previews in the Explorer shell and Outlook 2007/2010.

Fortunately, Leo Davidson has solved the problem and developed a little utility to fix the Adobe PDF preview control on x64 Windows.

Wow. This installer defect has been there for what, 2 1/2 years. Seriously Adobe, this is just sad. Please fix it and while you are at it, send a nice thank you to Leo for solving the issue.
