Microsoft DirectX


Topo USA requires Microsoft DirectX to run. Due to constantly changing technologies, DirectX can be sensitive to certain video and audio drivers. Consult your computer manual or contact your driver manufacturer to ensure that you have the most current versions of your drivers.


During installation of Topo USA, you have three options. If you already have DirectX on your computer, install the full version of Topo USA without DirectX. If you do not want DirectX on your computer, install the 2-D version of Topo USA (The 3-D features will be disabled.). If you want to install DirectX with Topo USA, install the full version of Topo USA with DirectX 5.0 option.


The most recent version of DirectX can be obtained from Should you encounter problems when using DirectX 5.0, you can restore your original drivers. Any problems with any version of DirectX should be directed to Microsoft at or 800-936-4200.

2. In the Add/Remove Programs properties dialog box, click DirectX Drivers to select it and then click the Add/Remove button.

3. In the DirectX Setup dialog box, click the Restore Audio Drivers button to restore your original audio drivers.

Program will not install or stops working


To ensure that the program installs and runs correctly, make certain the CD is free of all foreign particles. Even if the disc is not visibly dirty, it is helpful to wash it. To properly clean a disc:


1. Run it under warm tap water.

2. Use a mild dish soap and a soft cloth to cleanse, wiping across the CD rather than in a circular motion.

3. Rinse well.

4. Dry completely with a clean cloth.

5. Exit out of all active programs and shut down all TSR programs before reinstalling.

Troubleshooting installation problems


If you are receiving errors during the installation, please make sure that all background applications are shut down before running the installation for Topo USA. Programs that cause the greatest concern are Anti-Virus, Uninstaller and Mail Services.



Changing CDs


Topo USA gives you coverage up to mag 9 for the entire United States on each CD. To view more detail (mags 10-16) for a particular area you must be using the CD for that region. To change CDs, close the program and insert the desired CD.





If you open a previously saved route that is in an area that is not on the current CD, you will not be able to create a Profile for that route. Close the program and change the CD to the appropropriate region.


The Profile does not display accurate elevations for water features (e.g., lakes, rivers, oceans). It only works for land features.



DeskJet or Inkjet Printing Tips


You should acquire the latest driver from the printer manufacturer.

In both operating systems, we recommend using the

default driver settings, and printing in Econo mode to conserve ink.


Note: For Canon BJC printers, go to the Graphics Tab, click Custom, and select Diffusion.



Laser Printing Tips


If you are having problems printing to your laser printer and you experience

any of the following: "error 21" message, "print overrun" message, or

partial map printing, verify that your printer has enough memory. To print at 300 dpi you need 1.5 MB or more of printer RAM, and to print at 600 dpi, you need 6 MB or more of printer RAM.


Also, before printing, from the Print dialog box, select the Options or Properties. Make sure that you set the Graphics Mode to Raster (if available) and that you enable the Print TrueType as Graphics option for Fonts.



GPS Demo


The file, DEMO.GPL, is a sample log file located in the install

directory. It can be loaded by clicking the GPS tool, selecting Track from Log... Track from Log, and opening demo.gpl. For best results we recommend that you first calculate a route from Manchester, ME to Locke Mills, Me. This is the same route used to compile this sample log file. If you calculate this route first, you will be able to watch as Topo USA determines what road you are on and what your next road change should be.



Street Atlas USA 5.0 GPS Users


When you install Topo USA, the GPS features of Street Atlas USA 5.0 will be upgraded to a new and improved version. In this upgrade process, your Street Atlas USA 5.0 GPS operations are neither deleted nor overridden, so if you uninstall Topo USA, your GPS features will return to their original Street Atlas USA 5.0 configuration.



Palm Computing and Windows CE Operations


If you have HotSync or Active Sync loaded in the startup (the default configuration) it will reserve the COM port. If that is the one where the GPS is plugged in, you will need to exit HotSync/Active Sync to get the GPS to initialize. This can be done by clicking the HotSync/Active Sync icon on the task bar.



Palm Computing Users


The Topo USA directory contains the sample map and Route Directions files, Solus.PDB and Solus-Map.PDB. HotSync these files to your organizer after Solus Pro for 3Com Palm Computing has been installed.



Sending Maps to a Handheld Computer


If you open a previously saved route to send to a handheld computer, you must be using the appropriate CD for the region containing the route.




The following file can be found in the Topo USA directory.


CDTOPO.EXE - this should be used when you have multiple CD drives and want to swap among the CDs with the program running.
