Ema we're usually having to remind people to:

a) READ THE README FILE (procedures may differ with each download**)

b) Some downloads, like this one, will automatically install to C:\Games\ (it shows that it's doing that in the install pop up AND tells you that in the README)
NOT in Documents, in C:\Games\ .... unless you SPECIFICALLY change the path to a preferred location which you can do using the BROWSE button on the popup.

However, it sounds as if you were aware that it was defaulting, so if you can't find it, the easiest way find it is to search your drive for - EChess.exe

Then, you'll have to manually create a shortcut to launch the game, and "create a shortcut" by rightclicking it.

** Today's README.txt SEZ -
Unzip the package you`ve downloaded and install the software by running
Setup.exe. Please, make a note of where the game is installed (there won't be
any desktop shortcut created). By default game installs to C:\Games\

I looked in games in documents i have the download on desk top and installed but cant find where to start it
