Have you tried right clicking on the url on the browser you are using and saving directly to the disk?

Does that only happen with PDF files?  Other downloads are ok?

What is your operating system, b.t.w.?

Ok, let's try something...

Go to http://forums.adobe.com/community/flashplayer?view=documents and download the top document.  On Windows 7 it should automatically go to %userprofile%\Downloads - the file name will be DOC-1451.

Now open Windows Explorer and try to open the document; still the same error message?

If yes, right-click on the saved document and select Properties.

• what is the file size?  (It should be 98,084 bytes.)
• on the Security tab, what are the permissions for your userid?  (It shouls at least have Read, Write, Modify.)
• on the Details tab, what are the Attributes?  (It should just have an A.)

See the corrected instructions two posts down.

Ok, let's try this again...

Go to http://forums.adobe.com/docs/DOC-1451 and download the PDF document.  On Windows 7 it should automatically go to %userprofile%\Downloads - the file name will be flp_local_settings_manager.pdf

Now open Windows Explorer and try to open the document; still the same error message?

If yes, right-click on the saved document and select Properties.

• what is the file size?  (It should be 222,664 bytes.)
• on the Security tab, what are the permissions for your userid?  (It should at least have Read, Write, Modify.)
• on the Details tab, what are the Attributes?  (It should just have an A.)

Take your time; I also have to go away now (getting a haircut).

Can you open Adobe Reader by itself?

If yes, can you try to open that downloaded document from within the running Reader?

If you still get the same error, can you try to open that document with another application, e.g. Notepad?  (Just to see if it results in the same error; you won't see anything useful in Notepad.)
