Windows Doc Viewer & .NET framework

While trying to run Windows Movie maker… i try to move a section of video to the movie timeline… and then a box pops up and says that i don't have the right kind of Windows Document Viewer and trys to find a place for me to install it automatically… but it fails and switches to a new pop-up telling me that "The feature you are trying to use is on a network resource that is unavailable."— Any advise on what to do???

Also… when i startup my computer… a pop-up comes up that says something about me missing a .NET framework that is "necessary" for me to run this computer properly. — I don't know if this is good or bad… or does it mean anything at all???

PLEASE ADVISE —9h03n1x—

Well, if its "necessary" to run properly the its hardly gonna be good is it :p and did the errors come with any error codes?

yah… lets see… Error number 1706… code v1.1.4322
