Using Office 2007 and Windows Live Mail, when I double-click on an attached Word document, Word opens, then minimises itself with message “can’t send document to program”. A 2nd d-click works, however (perhaps because Word is open but minimised).
The best way would be to download the word document, than open it..
This sometimes happen from UAC (user control accounts)..
But also, when you open the document, it download temporary, and after office is opened, the temporary opened file, has been deleted.. This happens for other reasons, that are too long to explain here.. But, please, try downloading the office docs before opening, since it's better!
Check the following link it may help
Thanks for taking the trouble to reply with that link! Unfortunately it didn't solve the problem, and so I decided to use Syastem Restor to replace all my Word user settings.
