Your computer is full.......................
Use disk cleanup and delete programs and games that you do not use anymore. Go to “My Computer” and select C:\ right-click and go to properties. How much room do you have, i think the sims2 requires 2.5gb of free space. If you dont have at least that, make room for it.
NOTE: I’m assuming its C:\ if it not just change C:\ to the drive that you are installing too.
an error message keeps on coming up saying, 'there is not enough space available on drive to install the game. Please free up some space or change the target location to a different disk.' can some1 plz plz help me plz!!!!????
