I have a hyperlink to a PDF file, that when clicked gives me the usual "Some files may contain a virus..." warning, but then gives me a "No program is registered to open this file." message...
I have the latest Adobe Reader installed, and the file opens without problems from any other location (just not from Excel)...
Other hyperlinked file types open fine from within the same worksheet.
PDF is listed in Control Panel > Folder Options > File Types, and is associated to Adobe Reader...
Any ideas?
