Can't open Norton. Error messages: Missing MSVCP100.dll and Norton error 8504,104

All of a sudden I can't open Norton Security Suite and I get the message about missing MSVCP100.dll.  I used the Norton fix program and it didn't find anything.  I have found a few posts about this and tried the fix program suggestion but I am not seeing much more help about it.  Maybe because I don't understand what they are talking about.  Can anyone help?  Thanks
