SIMATIC STEP 7 V5.5 and other SIMATIC software products released for Windows 7 already include the required driver for the SIMATIC USB Prommer and the PC Adapter USB (part of SIMATIC Device Drivers).

In SIMATIC STEP 7 V5.5 and other SIMATIC software products released for Windows 7, the required driver for the SIMATIC USB Prommer and the PC Adapter USB are part of SIMATIC Device Drivers. A separate installation of the drivers as before via the CD supplied together with the PC Adapter resp. USB Prommer is thus no longer necessary.

The version of the SIMATIC Device Drivers can be determined via the SIMATIC Manager as follows:

Help Menue -> Info -> Installed Software: Display -> Tab "Components"

If version ≥ 8.1.5 is displayed for SIMATIC Device Drivers, the require driver is available already. Installation of the CD USB-Prommer 10/2007 / PC Adapter USB 10/2007 is not necessary in this case and will be aborted with the following error message: "The conditions for a successful installation are not fulfilled. Version V8.1 is installed on your computer. This Setup cannot install version V2.0 over V8.1"

Windows 7
For Windows 7 you must use the drivers from the SIMATIC Device Drivers. The driver on the CD USB Prommer 10/2007 / PC Adapter USB 10/2007 is not released for Windows 7.
