MORE INFORMATION

NOTE: This issue affects the Umax Astra 2000U and 4000U scanners.

Upgrade or Fresh Install

There is a difference in behavior in the installation of scanner drivers in the following situations:

Situation 1: When you upgrade to Microsoft Windows Millennium Edition (Me) from a previous version of Windows.
Situation 2: When you perform a fresh install of Windows Me (with no previous operating system installed).

Situation 1:

After a migration from Microsoft Windows 95, Microsoft Windows 98, or Windows 98 Second Edition, no WIA driver is installed because the independent hardware vendor (IHV) driver is detected and retained. In this scenario, VistaScan functions as expected because the Umax driver is still being used.

Situation 2:

When you connect the scanner to the computer, the WIA device drivers for the scanner are installed. In this scenario, all WIA functionality performs as expected, but the Umax VistaScan software no longer functions properly. This is because the Umax VistaScan software does not recognize the WIA scanner driver. The VistaScan software requires the IHV driver to function properly.

WIA is a new imaging architecture, introduced in Windows Me, which allows imaging programs to communicate with imaging devices. For more information on WIA, visit the following Microsoft Web site:
