Application Not Found Error when openning Outlook 2003 Attachments

[tmpotvin]

Good Afternoon,
We have some users who receive files from our financial systems daily that
are PDF files, but the file extension is not PDF. The system has always
worked like this, and the users would select Adobe Reader from the list when
openning the file, however, ever since updating to Adobe Reader 9.3 from 7,
Outlook simply gives an "Application Not Found" error mesage.
I have tried cleaning the Temporary Outlook Files and that will work for a
few files, but none of the other ones worked. Also, the file is a different
name each time so having the user clear that each time seems a bit much.
When the user saves the file locally from Outlook and then opens it, there
are no issues, it just seems as though Outlook is holding on to an old
setting somewhere pointing to the old version of Adobe Reader and wants to
call that instead of prompting to use a specific program to open.
Has anyone run in to this before and have any suggestions?

Thanks!!

Outlook follows the file associations set in Windows; it does not keep its
own list.

If they are pdf-files, why aren't the extensions pdf either? What is it
then?
You can of course associate that extension to always open with Adobe Reader.
