I am not able to install Microsoft Alphabet Playhouse on Windows 7. It was working fine on Win98 and win2000. After upgrading the system to XP and now on Windows 7, I am not able to install it.
Getting a Windows 98/2000 application to run on Windows 7 could be somewhat hard because of compatibility problems. Try to install VirtualBox and create a virtual machine with Windows XP installed. You can add the software to that location if you want to run it on Windows 7.
