Updating the Flasher LT Windows Drivers
Make sure the drivers are accessible on the PC being updated,
either by having a drivers CD in the CD-ROM device or unzipping
the drivers file from the Bosch Diagnostics website to a known
location on the computer.
Connect the Flasher LT to a USB port on your PC.
Open the Windows Control panel, double click on the System
icon, choose the Hardware tab, and click on Device Manager.
From the Device Manager Window that opens up, click on the +
sign next to Universal Serial Bus Controllers.
Locate and right-click the Flasher LT entry and choose Update
Choose "No, not this time" if prompted to connect to Windows
Update to search for drivers.
If Windows XP, select "Install from a List or Known Location", if
Windows 2000 this will be automatic.
Check "Include this location in the search" and browse to the
directory where the Bosch Diagnostics Drivers were unzipped to
and click NEXT
The new Windows drivers should install normally.
