I have created a series of hyperlinks to PDF files in my Excel file. But when
I click on it, Adobe starts and then closes immediately without opening the
PDF file. For hyperlinks with Office documents (such as Word or Powerpoint)
this problem does not occur.

On the Microsoft support website, it says that this problem occurs if Adobe
Reader 7.0 is installed on the computer, and the problem can be solved by
installing the 7.0.1 update.

I am using Adobe Professional 7.0, and the "Check for updates now" is
telling me that there are no updates available. Is there anything else I can
do? Thanks.
