Welcome to the CDXZipStream February 2011 Newsletter


We've just released another easy-to-use "one-click" template for reverse geocoding, which can take a long list of latitude/longitude points (such as those downloaded from a GPS) and find the closest address for each.  And by customer request, we provide step-by-step instructions on how to reinstall CDXZipStream on a new computer or laptop.

 Here are our new blog articles from this past month:

How to Reinstall CDXZipStream on a New Computer


We often get phone calls from registered users asking how to reinstall CDXZipStream on a newly purchased computer.  Our license agreement is set up on a per user basis, not by computer, so there is no problem doing this.  This also means that you can install CDXZipStream on a spare computer such as a laptop.   This can also be handy when you are doing long calculations such as routing with MapPoint where you do not want to tie up your main pc.  Our license does not permit sharing with other users on these additional machines.


To set up CDXZipStream on a new computer simply download and install the CDXZipStream demo on the new computer.  When installation is complete and Microsoft Excel opens, press the third button on the CDXZipStream toolbar named "Licenses and Software Updates". (If you are using Excel 2007 or 2010, the CDXZipStream toolbar is located under the "Add-Ins" menu.) Then press the "Buy Now" button followed by pressing "Generate KeyCode" and log into our web site using the username and password you received with your original purchase.  If you did not retain your original purchase information please contact us at


A web page allowing you to generate a new keycode should appear with your new Computer ID automatically entered. This Computer ID is unique for each PC and your registration code is based on it. Then press "Next" to generate your new registration key.


Copy your new keycode from the box that appears and then press the "x" in the upper right corner and minimize your browser. Then paste the copied code into the "Keycode" section of the "CDXZipStream Purchase and Registration" box and press "OK". (This is the box where you pressed the "Generate Keycode" button.) CDXZipStream will now be fully activated on your computer.


Your online account can also be used to purchase data updates or upgrade your product to a more powerful version.  A history of all data purchases is maintained in the "Download Data Files" section.


Easy Reverse Geocoding in a One-Click Template
Reverse Geocode

As another addition to our series of easy-to-use, one-click Excel templates, we now have a reverse geocoding template.  Reverse geocoding, which identifies the closest address to a geocode (latitude and longitude) point, is a critical component of mobile location-based services. The template is a free download from our website, and can be tested with free trials of CDXZipStream and Microsoft MapPoint; links to free trials for both are available within the template itself.  


To use the template, enter the geocode points of interest, or you can copy and paste them from another application. Then just click the button "Reverse Geocode"  and the calculations proceed automatically. Long lists of points can be geocoded very quickly, and no special knowledge or computer skills are required.  For a quick demonstration, please see our short YourTube video Reverse Geocode Template for Microsoft Excel.

Many more templates to help automate common tasks with CDXZipstream are available on our website. The templates help automates tasks such as closest zip analysis, driving distance, geocoding, route optimization and much, much more. The templates are much simpler to use for large scale analysis than entering the formulas yourself. Calculations such as route distances can take a long time to run and the templates will show calculation progress and allow to cancel the operation at any time. Just copy in your data and click a buttton to use them.
