Safari PDF problem

Clicking on a link in safari to open a PDF file, I get an error message saying "Adobe PDF viewer can not find a compatible Adobe Acrobat or Adobe reader to view this program".
I have tried going into preferences to set a program to open, could not find the setting area. Firefox uses Preview with no problems.
Any suggestions appreciated. Thanks

Same situation & more

I have the same situation. I tried installing Adobe 9.1. Installation seemed to work until I tried to open a PDF file through Safari and got the same message as vince0501. Tried opening Adobe and got "an internal error has occured."
Any ideas?

In my opinion, Adobe is awful. They released an update today (FINALLY) for a security hole found awhile ago. Why not use the built-in Preview?

Thanks for the reply. I just tried opening a pdf link on Safari and got the message "Adobe PDF viewer can not find a compatible Adobe Acrobat or Adobe reader to view this program".
How do I set Preview as the default?

I believe this is how you do it:

1. Close Safari.
2. Open Adobe Reader
3. Go to Preferences->Internet and uncheck the box next to Display PDF in Browser using Adobe Reader.

This should then cause Safari to use Preview by default.

I don't have Adobe.
