Can't update through impulse

I purchased this game a few weeks ago, I have been trying to update the game through impulse, every time I try, it says it downloads the update, I click install all updates on the bar, it installs some files, but it keeps showing installed version 1.00.00

am I doing something wrong?  I have done this about 10 times, where it keeps installing the update, but it still shows version 1.00.00
