Software Errors
Q. I have a USB software key installed, but my program gives a "key not found" or ""key not authorized for this product" message. The LED in the software key may be flashing.
A1. Connect the key to a different USB port on the computer, and retry the program.
A2. The driver for the USB key is not correctly installed. Use the following procedure to reinitialize the driver.
NOTE: Administrator privileges may be needed to complete this procedure.
1) Make sure that an appropriate Scribner Associates, Inc. software is installed on the PC. This may include CorrWare, CorrView, ZPlot, ZView, or MultiStat. Versions can be checked by choosing Help | About from inside any of the applications.
CorrWare/ CorrView/ ZPlot/ ZView should be V2.9 or later
MultiStat should be V1.2 or later
2) Close all applications. Connect the key to the PC.
3) In Windows, choose Start | Control Panel and then System
4) From the System Properties dialog, choose Hardware and then Device Manager
5) Locate the ROCKEY listing as shown below. Note that it may be listed under "Other".
6) Highlight the ROCKEY listing and choose Action | Uninstall.
NOTE: This does NOT remove software from the PC. It only resets the driver configuration.
If ROCKEY4 is listed multiple times, uninstall the ROCKEY4-USB items first, and then uninstall any other ROCKEY4 items.
7) Disconnect the USB key.
8) Go to C:\SAI\Programs (the default location of the Scribner Associates applications), and run the program named KEINSTALL.EXE
9) From the KeyInstall application, choose UNINSTALL. After the uninstall is completed, choose INSTALL.
10) Reboot the computer.
11) Connect the software key.
Windows should display a "Found New Hardware" message and will automatically install the driver.
The LED in the software key should be on continuously (not flashing).
Start CorrWare or ZPlot and choose Help | About. The serial number of the software key should be displayed. If the serial number is displayed, the software key is fully installed and ready to be used.
