Hello

I want to look for EXP_PDF.DLL file in the \Common Files\Microsoft Shared\OFFICE12\ folder and then create a customized message box whether the file exist or not. Now the challenges here is:
1. Micorosft office can be installed in a different folder (like in my case it is in, C:\Program Files (x86)\Common Files\microsoft shared\OFFICE12
2. It can be installed on a different drive (like in my laptop D:\Program Files\Common Files\microsoft shared\OFFICE12

How can I locate the default installation drive and folder path? What I need to do is, I need to find if PDF Addin is present on the system or not. If present, alert "Go ahead...." If not, message box with a link to download "PDF add is missing, please download from here" creating a link on the word 'here' that will take user to this url http://www.microsoft.com/en-us/downl...n.aspx?id=9943

Thank you
