Perhaps you installed a different variant - there are 3 variants for Windows - 32bit, 64bit and Portable. All three can be installed, any one of them can be executed on the same system, at any one point in time.
So you may have been running 0.9.7 32bit, now you've installed 1.22 64 bit , but you're clicking on a shortcut that refers to the 32bit variant.
