Decompile an .EXE file containing 1 Video

I purchased a .EXE file with a Video in it (150MB) , and the seller can't seem to get me a working password after trying a few times. I have another similar file, and when I enter the correct password, the video shows via Windows Media Player. I would like to decompile the .EXE file, and for the Video file to be sent back to me. If you need more information from me, please feel free to ask! P.S. i'm not sure if this is posted in the right category!
