Vista - Problems installing a game

I have today tried to install Medal of Honor Allied Assault Warchest, and I
am having a few problems. All was going to plan, and I had got onto the 2nd
disc when installing. About 75% of the way through the installation, my
Laptop crashed, as it often does. Upon restart, I had no prompts and and a
half installed game. And so i attempted to uninstall it and try again.
Through Programs and Features I clicked to uninstall after which it informed
me it had been successful. However, now every time I run the setup file to
install it, I'm presented with the same options as when trying to uninstall;
Modify, Repair and Remove. I have tried all three, all to no avail. The
directory in Program Files is no longer there and it isn't listed on my Start
menu. However it is still listed under Programs and Features, but only sized
at 1.20MB.

Any idea how I remove every aspect of this program so I am free to install
it again?


Thanks in advance
