In Windows Explorer type %TEMP% into the location box.
You should see a number of folders and many of them will be named fairly randomly. What you want to do is make sure you're in the details view mode and sort by date modified (descending). The folder you want should be very close to the top, just look in each one until you find a file named defenders_quest_0_9_1.exe
Pretty sure that the correct filename. It should be close to that anyway. You might have to keep the game running in the background until you've found the file to keep windows from cleaning up the 'temporary' file. If that's the case you can move the file to your desktop then close DQ before you actually run the file.
Like the devs said in the update threads, the newer versions of the game handle this process better.
