I can't find out much about these games. According to the dates at Amazon, Uncle Albert's Fabulous Voyage and Uncle Albert's Mysterious Island were released in 2001. So the games probably use QuickTime 4 or 5. I don't know if these versions of QuickTime will work in Windows 7. The games would have been made for Windows 98/ME or Mac OS 9.
If you're not able to uninstall your current version of QuickTime and install the version that came with the game, about all you can do is try playing the games in Windows 98 compatibility mode and set them to run in 640x480 or 800x600 (whichever the games use, though since you say the games appear as a tiny "square" and not a rectangle the resolution may not be the problem. If the games appeared as a tiny rectangle it could simply be the result of playing a 640x480 game on a 1900x1200 screen (or similar high resolution screen), and that problem is usually fixed by adjusting the resolution to what the game uses.)
If compatibility mode doesn't work, installing Virtual PC with Win 98 inside and playing it inside a virtual machine may be the only way to play it on a Windows 7 computer. It's pretty sure to run in that because the game will actually be running on Windows 98, though inside an emulator. However it takes some time to set up. If you're interested, there are instructions for installing Virtual PC 2007 with a Windows 98 Virtual Machine
