All Thank you for any assistance. I'm pretty familiar with Windows 7, computers in general. I have a weird issue with trying to associate file extensions to .torrent files and to .xls, .doc and other microsoft office file associations. I have recently installed Office 2007. Issue is that I try to change file association to open with anything other than "Windows shell common dll" and cannot. I try to browse to excel.exe to manually apply file extension but this proves futile as well. I've tried using the file unassociation tool from How to unassociate File Type Extensions in Windows 7 and Vista. but this does not do the trick either. Other files .zip, .exe, ect.... I have no issue with. Pretty frustrating to say the least.
