Data Transfer Error during installation
If you receive a Data Transfer Error dialog box during a Windows 95/98/ME/NT/2000 installation, exit the install and shut down all other applications. In most cases, this is due to a .DLL (Dynamic Link Library) file that is still in use while the install program is trying to update it. It may also help to log off the system and log in again before retrying the installation.
