Resetting the default application outlook 2010 uses to open PDFs


I have a laptop loaded with Win 7 x86 and office 2010. Before Acrobat was installed I tried to open a PDF from within outlook (preview pane and open message) and when asked to choose a program with which to open it accidentally clicked windows media center.

After installing Acrobat all other PDFs can be opened via Acrobat and it is set as my system's default program. But each time I try to open a PDF from within outlook it opens it with WMC.

After uninstalling WMC nothing happens when you double click a PDF attachment in outlook.

any ideas?

Try resetting the association between pdf and WMC.

Or do it in registry, see the "Edit the Registry" in following link:

I suggest you try to official way first before hacking into registry.

thanks. remember that all pdfs are opened by acrobat other than when opened via outlook so the association thing correctly configured.

the problem is only via outlook. does outlook have it's own file association setting?
Try start Outlook with switch /cleanprofile or /firstrun and see if that helps

Well, AFAIK Outlook uses the Windows' association and doesn't have it's own setting. But I'm sure only for versions upto 2007, not for 2010. Though after a quick look at the WWW I don't see anything to suggest that 2010 has it's own association.
Did you already try resetting the Windows' association?

in the end i solved it in the following manner:

i opened a new email and tried to attach a pdf. while in the attachment window i selected a pdf and did open with acrobat.

i then got a protected mode dialogue box which required me to select the option that ignores protected mode altogether.

seems to have fixed the problem.

thanks to all but in the end i think i did this one myself. anyone disagree?
