That's not a name for the file
"Fallout3_1.7_English_US.exe" is a name for a file, and should be the name of the one you are using.
The exact error message would be helpful too, if there is one. Vagueness does you no good in these situations.
At any rate, first thing I'd try would be getting an updated install of Games For Windows Live from Microsoft's website. Install that first and then try the patch.
