This was also posted by a user at amazon. I couldn't find the "Use an older
program with this version of Windows" selection, but I'm sure running
compatability mode will give you the same options. I guess Run As
Administrator might be helpful too.
It's a little frustrating trying to get "Where in the World is Carmen
Sandiego?" to work in the Windows Vista environment. Here is a useful
workaround.
Go to the Start Menu and select "Control Panel". Click on "Programs". Under
Programs and Features, choose "Use an older program with this version of
Windows" and select "Where in the World is Carmen Sandiego?" from the list
of programs. You will now have several options as to how you want the game
to run. I found that the game worked best in the Windows 98 environment,
with the display set to 640x480 with 256 colors. When you're done setting
the game up, right click on the Carmen Sandiego shortcut and select "Run as
Administrator". Wallah!
The game itself is fun (once you get it to run). I was expecting a more
modern version of the game (i.e. similar to what I found in the Elementary
Advantage software pack) but for the price, it's not bad.
