TeslaMap Support

Please refer to this list of common issues and solutions if you experience an issue with the TeslaMap program. Please contact me if your particular issue is not listed.

I get the error message "Could not find main class" or "A Java Exception has occurred".

You did not extract the TeslaMap.zip file or you successfully extracted the zip file, but are still trying to run the TeslaMap.jar file in the zip folder, not the extracted folder. Please visit the step-by-step install guide.

This error can also be caused if the TeslaMap.jar file was moved out of the TeslaMap folder. If you would like to move the program to a different directory on your computer, either move the TeslaMap folder or create a shortcut to the TeslaMap.jar file.

I get the error message "Windows could not open this file".

Download and install the free Java Runtime Environment from Sun Microsystems. TeslaMap is written in Java and requires the JRE to run.

When downloading or installing TeslaMap I get a warning message about viruses, malicious code, unknown publishers and stuff like that.
Is TeslaMap a virus?

I can assure you that TeslaMap is not a virus. TeslaMap has been verified by Softpedia.com and VirSCAN.org to be virus free. PayPal does not allow people to sell viruses through their service. Please use virustotal.com to scan TeslaMap with 56 anti-virus programs.

I created and began distributing TeslaMap over 10 years ago. Check my old websites in the Wayback Machine Internet Archive from 2006 (but please don't laugh at my old websites). Also check my teslamap.com domain registration information. Of course, I'm biased so please search the internet forums to see if people have had issues with TeslaMap. People that try to distribute a virus generally try to hide themselves - but you can contact me anytime and I'll be happy to respond :-) It's probably safe to say that I couldn't distribute a virus for over 10 years without someone catching on!

For a bit more technical detail... It's recommended that software programs like TeslaMap be "signed" with a "code signing certificate" purchased from a "certificate authority". The certificate is used to establish a trusted reputation. Once the signed software becomes trusted, users (that's you) won't see all the warning messages about viruses. Unfortunately, it costs several hundred dollars / year for a certificate. That's fine for large companies, but sadly, since TeslaMap is low volume, low priced software - several hundred dollars a year is not an economically viable option for me. In addition, I'm required to prove my identity by providing very personal information to the company that issues my certificate. Frankly, I don't trust them with my personal info. The process often takes several weeks of waiting. Then, the certificate must be periodically renewed (which requires more money). Also, the process of actually signing the TeslaMap code is fairly complex. So due to the costs and difficulties involved in obtaining a certificate, I've chosen not to sign the TeslaMap program. So don't ignore those warning messages, but please consider that TeslaMap has been around for over 10 years and it's been verified by Softpedia.com, VirSCAN.org and 56 anti-virus programs to be virus free.

I get the error message ".NET Framework Initialization Error".

Please install the free .NET Framework from Microsoft.

When I run TeslaMap.jar I see a black box that disappears.

The jar file is probably not associated with the Java Runtime Environment (JRE). The association should be set automatically when the JRE is installed. Download and install the free Java Runtime Environment from Sun Microsystems.

If TeslaMap still fails to run please follow these directions...

Windows Vista / 7:
Start Button → Control Panel → Default Programs → Associate a file type or protocol with a program → Select .jar → click the Change program button → select Java Platform SE Binary → click OK

Windows XP:
Start Button → Control Panel → Folder Options → File Types tab → select JAR in the list → click the Change button → select Java Platform SE Binary → click OK

I paid for the program but didn't immediately receive it.

I apologize for the inconvenience. On rare occasions PayPal does not properly forward to the download page. Please contact me and I'll resolve the issue as soon as possible.

I downloaded the full version but the evaluation version still runs.

It's easy to mix up the full version and the evaluation version. Please delete the evaluation version of TeslaMap from your computer. You may also return to the download page and re-download the full version - but the download page will only be available for a limited time.

My output is strange or missing.

Try adjusting the Menu → Set Location option or changing your thousands separator between comma and decimal points. Different locations use different decimal point or digit group separators. Internationally, they have both been used for both meanings. The TeslaMap program will try to detect your location and use the local convention.

Step-By-Step Install Guide

(Version 1.18 zip file)

Please follow these steps...

Note - This guide assumes you are using Windows. This guide was made with Windows 7, other versions of Windows may vary slightly.

Download the TeslaMap program or the free evaluation version. The file you download will be called TeslaMap1.18.zip (or something very similar). I recommend you save the downloaded TeslaMap.zip file to your desktop.

When the download is complete you will have a TeslaMap1.18.zip file on your computer.

folder

Right-click on the TeslaMap1.18.zip file and a menu will appear.

menu

Select "Extract All..." in the menu.

The Windows Extraction Wizard window will appear.

extract

Select the location where you would like the TeslaMap program to be placed, or just accept the default location. Be sure to make a note of this location because we'll be going there next.

Click the extract button.

A new TeslaMap folder will be created in the location you specified in the Windows Extraction Wizard.

folder

Open the new TeslaMap folder. (It may have opened automatically if the "Show extracted files when complete" box was checked in the Extraction Wizard.)

Inside you will see a TeslaMap.jar file.

folder

Double-click the TeslaMap.jar file to run the TeslaMap program.

If TeslaMap Fails To Run

Please try the following...

Download and install the free Java Runtime Environment from Sun Microsystems.

If TeslaMap still fails to run, the .jar file type is probably not associated with a Java Runtime Environment (JRE) on your computer. To fix this please follow these directions...

Windows Vista / 7:
Start Button > Control Panel > Default Programs > Associate a file type or protocol with a program > Select .jar > click the Change program button > select Java Platform SE Binary > click OK

Windows XP:
Start Button > Control Panel > Folder Options > File Types tab > select JAR in the list > click the Change button > select Java Platform SE Binary > click OK

Try restarting your computer.

Be sure you are extracting the TeslaMap.zip file, not just opening it. If you try to run the TeslaMap.jar file without extracting it, you'll get the following error...

java error
(Version 1.18 exe file)

Simply double click the TeslaMap1.18.exe file to start the installer. The installer will guide you through the install process.

(Version 8 exe file)

This version does not need to be installed. Simply double click the TeslaMap8.0.X.exe file to run the program.

If you encounter this error:

net error

Please install the latest .NET Framework from Microsoft (free).
