Have you experienced an installation problem?   

The first time installation can be the most difficult part of using our software...


We provide the solutions to the most common installation problems below.


Let us know if you have other problems by emailing support@digistamp.com. Support will need to know if you are able to run these simple tests.


Installation issues:

The installation is easier with MS Internet Explorer.

  1. Did Java Web Start get properly installed?
  2. Users of Google Chrome
  3. Your browser is asking dowloading or file download and the software does not begin?
  4. Check if Java is installed on your computer.
  5. Seeing the message "Unable to launch IP protector"
  6. Proxy Server and Firewall considerations
  7. Minimum system requirements
  8. Other Technical Problems
  9. What is a JNLP file?
  • Did Java Web Start get properly installed? 

Is this a problem with the Digistamp software, or a more general issue with the Java environment on your computer? This is an easy test. Using the link below, you go to the Apple or Sun Microsystems web site and try to run their simple demo applications:


Java Web Start simple test 

 

  • Google Chrome Users

Google Chrome does not support Java Web Start launches by default.  After clicking to run our application you will likely see.

Proceed with the download by selecting "Keep".  You may now click the IProtect.jnlp to run the program or configure Chrome to run the IP Protector and other jnlp files in the future.

 

You can configure Chrome to run Java Web Start programs by reconfiguring the following option:

  • Your browser is asking dowloading or file download

If you see one of the messages below then the Java Web Start is not properly installed. As a test, you can compare the windows below after you click here: Run the application. Cancel out of the window that is shown or press "back". Google Chrome users should go here to resolve. MS Internet explorer should go here to resolve.

  • Check if Java is installed on your computer.

A simple test to check if Java is installed is by entering this command on the command line:

 

On Windows enter: java -version

 

You should see something very similar to this:

java version "1.6.0_07"

Java(TM) SE Runtime Environment (build 1.6.0_07-b06)

Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

If you need to install Java, access the Sun web site for Java Installation here and complete the installation. This link includes some abilities to check if you already have Java and if you need to upgrade.

  • Message "Unable to launch IP protector"

The above message is sometimes combined with the message "The following file is missing"

 

This problems has been observed when the Java Web Start proxy settings are incorrectly set. You can check the setting in the Java Web Start Application Manager.

Java Web Start application managers uses the Internet to retrieve the software. The installation process attempts to copy the settings of your Browser into the Web Start environment.

 

  • Proxy Server and Firewall considerations.

Proxy servers are used in some network configurations - for example, users in a corporate office environment. Java Web Start software must be configured with the correct proxy settings in order to launch applications from outside your firewall. Java Web Start software will automatically try to detect the proxy settings from the default browser on your system. Sun provides some documentation to help you configure your computer to use a proxy server here.

 

  • Minimum system requirements.

Java is a language designed to run on multiple platforms (different OS, CPU, browsers) but does have minimum requirements. These are:

  • Minimum of 32MB RAM for the virtual machine. This means that you would require at least 64MB RAM for your machine to be able to run any application satisfactorily.
  • Minimum of 300MHz Pentium II class machine or higher. AMD K6-2 of 350MHz or higher.
  • Minimum of Graphics card capable of 16bit color.

 

  • Other Technical Problems

Sun Microsystems has provided problem diagnostic help for Web Start here.

We can also be of assistance and appreciate any feedback about your experiences, contact support@DigiStamp.com. Please provide information about your specific experience, including, for example:

  • Type and version of the operating system you are using (example: Windows 7 64-bit, Vista 32-bit, Service Pack 6a – Red Hat Linux 7.3 Desktop) Go to Windows Explorer, About or System Information.
  • Type and version of the browser you are using (go to the About screen, example: Internet Explorer 6.0sp1 – Mozilla v1.1)

We make the web site usable for as many browsers, operating systems and platforms as possible, and we appreciate notification of any platform-specific problems.

 

  • What is a "JNLP" file?

Our IP-Protector software uses a JNLP file to start the application. An analogy may be helpful to describe the purpose of the JNLP file: A file whose name ends with .PDF means that it can be opened with Acrobat Reader. Your Internet browser knows to use the Acrobat Reader program (a browser plug-in) to display a .PDF file. A file of type .JNLP means that your browser should use Java to open the .JNLP file. The installation process on our web site does two things: 1. Installs Java 2. Associates the file type of .JNLP with Java.

The content if the JNLP file is a primarily the name of the software and a pointer to where the software is stored on your computer.


When you are at our web page and click on "just click and go", this is a JNLP file that you clicked on. If all is installed properly, then Java should start and run the application. If Java is not installed properly, the browser will as you if you want to download the file because it does not know there is another program (a plug-in) that should be used to open the .JNLP file.
