Hi,
From the description, you want to set ACDSEE as the default program to open image files on your computer, correct? If this is the case, we can achieve the goal by changing the association of image files to association in Control Panel. See:
http://windows.microsoft.com/en-in/windows/change-default-programs#1TC=windows-7
Since this forum is for general questions and feedback related to Outlook, if you need further assistance regarding this issue, I'd recommend you contact the support of ACDSEE or post a new question in the Windows Client forum:
https://social.technet.microsoft.com/Forums/windows/en-US/home?category=w7itpro%2Cw8itpro%2Cwindowsvistaitpro%2Cwindowsxpitpro%2Cwindowsintune
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
