Whenever we open Adobe Reader or any pdf file, we get a Microsoft Office Outlook dialog window as follows:
"Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client."
We can still open any pdf files. However this dialog window is a nuisance.
I have made sure that Outlook 2013 64bit is checked for Default Mail Client.
I have also implemented an Experts Exchange registry solution changing the Mail key default to Outlook64Bridge and created a key of Outlook64Bridge with key DLLPath and DLLPathEx with defaults of C:\Windows\System32\mapi32.dll.
What else can I do?
