When I try to play fish tycoon after installation it says it can't find fish tycoon.exe or one of it's componets. I checked and all the files in the zip I downloaded are there. what do I do?

How did you install it? To main memory or an expansion card? How much free memory do you have?

I had about 20 megabytes of free memory. I installed it by putting the cab file on my SD card. I installed it to main memory.

That should be plenty of free memory! Is there some reason that you used the .cab file rather than installing using FTSetup.exe? Usually it's only necessary to use the .cab file when the game won't install from your PC. I prefer using the PC setup, since it makes sure that everything is installed in the right place. You might want to try that to see if it makes a difference for you.

If you're still having trouble, please post back here.
