I have installed Sims Complete Collection on my new computer. Unfortunately, I am not able to save game and it is really a problem to play game like Sims without possibility to save current position. Only difference between this computer and the old one is operating system. On previous computer I had Windows XP Professional and on this one I have Vista. Do you have any suggestion about this problem?
This problem is definitely Vista related. Because many security improvements some actions are not allowed in Vista that were allowed on previous Microsoft operating systems. To bypass this problem you should run this game as administrator. Right click on game icon on desktop and click on Preferences. Click on find target and then right click on game executable file. In new window choose Run as Administrator and close window. Now you will be able to save the game.
