You are providing technical support to an end user, and uninstall the application, then remove the old database. Finally you install a new version of the software. But it is picking up the old data.

If you have a Windows 7 Home Premium Edition computer and would like to have Windows XP with Service Pack 3 on your computer, the easiest thing to do is upgrade your operating system to either Windows 7 Professional Edition or Windows 7 Ultimate Edition. Then once you have done this, install Windows XP Mode from Microsoft. This will allow you to easily install and run applications that will only work in Windows XP from within Windows 7.
If you run Windows Updates and it fails, or downloads are set to be installed when you shut down your computer and they do not install successfully, or you install some software such as Kaspersky Internet Security and the installation fails then there is a simple solution.
Make sure that the following services are running: Background Intelligent Transfer Service, SPP Notification Service (Windows 7), SL UI Notification Service (Windows Vista), Windows Event Log, Windows Modules Installer, and Windows Update.
When copying a lot of files from one location to another on Windows, using Windows Explorer is slow. A much faster solution is to use the xcopy MS-DOS command. It works beautifully, and has saved me a lot of time. The syntax is as follows:
C:\xcopy source destination switches
The switches are:
Copies files with the archive attribute set. This switch does not change the attribute.
Copies files with the archive attribute set, and turns off the archive attribute.
Copies files changed on or after the specified date.
Prompts you before creating each destination file.
Copies folders and subfolders except empty ones.
Copies any subfolder, even if it is empty.
Verifies each new file.
Prompts you to press a key before copying.
