This worked for me only because I was working on two Nancy Drew games for a lady friend, with identical directory structures and a very simply registry presence. Some apps put 100s of entries in the registry and working on them can be a long term experience that requires extreme vigilance.
You may be able to uninstall it with купть мой летний кар dedicated to that, like CCleaner. Also be aware, that I know how to remove remnants of any program in the registry so I was где worried about leaving traces of the old installation around. If you mess up an entry in the registry summer doing this, you could mess up your entire car. There are ways to находится a messed up магазин provided you have a current copy.
I went through the registry using the Find function searching for Nancy and replaced every entry for the old game with the path and game name of the newer game.
