Windows 7 - Outlook Office 2010 PDF Attachments not opening

I am using Office 2010 and have a problem thatI thought would be easy to fix but I was wrong!

I am able to open all attachments and preview them except PDF files. I used to be able to open/preview PDF files as well until I unchecked the box that says, " Always ask before opening this type of file" on the Open Mail Attachment (Exhibit 1).

Now all I get with PDF files is what you see in Exhibit 2.

I am using FoxIt Reader as default PDF reader but I get the same results when I make Adobe Reader the default.

I am familiar with making registry changes and have tried modifying the EditFlags key under HKEY_CLASSES_ROOT\FoxitReader.Document to both 00 00 01 00 and 00 00 00 00 neither made any difference to Outlook PDF Attachments.

Same for Adobe Reader when that was the default I modified HKEY_CLASSES_ROOT\AcroExch.Document to both 00 00 01 00 & 00 00 00 00...no change in Outlook.

All I want is for the PDF attachments to behave the same way all the other attachments behave.
Any help would be appreciated.

Please highlight FoxitReader.Document in regedit, right click - EXPORT, and post that reg file here.

Thx!

I have noticed that EditFlags (in case of FoxitReader.Document) should be REG_DWORD type,
but you have REG_BINARY (hex).
Please back it up, delete and make it REG_DWORD.

Don't know how I missed that.
Thank you!
