I have a customer that had a program written for them - it is in Access 2002 and is a .mde file; they tried to install it on a Vista Home Premium 64 bit system but the programmer said there were issues with Vista. We upgraded (not clean install) to Windows 7 Home Premium 64 bit; then did an Anytime Upgrade to Windows 7 Professional 64 bit. They also loaded Office 2010 Pro on the system. They also have had the programmer tried to reload his program. The program goes into Program Files (x86) and then its own directory. In Program Files, there is Office, Office 10 and Office 12.
If you double-click on the shortcut, it flashes on the screen for a millisecond and goes away. If you try to go into the folder and Open the program with Access 2002, it says Couldnt Find system.mdw; this file is required for setup. If I try to open it with Access 2010, it opens but hangs - programmer said it was the incompatibility between 2002 and 2010, which I would believe. It only doesnt work on this system; it does work on two other systems - one running Windows XP and the other running Windows 7 Home Premium 64 bit.
