 NPL Revision 4.3/5.0
Hints and Tips for NPL Resellers

This page contains some helpful Hints and Tips for successfully installing, updating and upgrading to NPL Revision 4.3/5.0. This new release has been a great success in saving time and money for many distributors.

How do I upgrade my Release 3.x and 4.x installations to Release 4.3/5.0?

All upgrades now employ the use of Niakwa's Universal Upgrade Procedure. The Universal Upgrade is a simple self-prompting procedure that eliminates the need for tracking and returning Gold Keys. First, in order to run a Universal Upgrade successfully, you need to supply us with certain information. The following items are required:

    1. Serial Number (from the old Gold Key) - Determined by SHOWNPL

    2. The Product Number (from the old Gold Key) - Determined by SHOWNPL

    3. Additional Users/License Capabilities to add - Determined by Vendor

For example, lets assume that you want to upgrade a four user 4.10 MS-DOS for Niakwa Supported Networks Gold Key to an eight user MS-Windows for Niakwa Supported Networks. The first thing to do is to run SHOWNPL on the system you intend to upgrade. In our example case, SHOWNPL will return the following information:

    Serial Number: 123456

    Product Number: 004?PLR0470

After obtaining this information, simply provide it to Niakwa (Sales Order Desk) and tell them that you would like to add MS-Windows to the upgraded Gold Key and increase the user limit to eight users.

Note: SHOWNPL is included on every current RunTime Package and Universal Upgrade.

Once you provide the above information to Niakwa, you will be sent a Universal Upgrade RunTime Package. This package will include (1) NPL Upgrade Diskette, (3) NPL RunTime Replacement Diskettes, and a Certificate of License and Authenticity containing an Upgrade Registration Code. The Upgrade Registration Code is prompted for by the Universal Upgrade and is used to validate the old Gold Key and new Replacement Gold Key information that you provided us in items 1, 2 and 3 above. For a complete discussion of the NPL Universal Upgrade procedure, refer to the NPL Release V Compendium or the NPL RunTime Package Installation Guide.

Do I need to recall security to my old NPL Gold Key before running the Universal Upgrade?

For all MS-DOS / MS-Windows based RunTimes, the Universal Upgrade procedure requires the old NPL Gold Key security to be recalled from the currently installed system. For all SCO OpenServer Unix/SCO Xenix based RunTimes, the Universal Upgrade procedure requires the old NPL Gold Key security to be installed on the currently installed system.

My customer has lost security on their system. Do I need a new Gold Key to upgrade their system?

In most cases, no. Have the customer run the RESET program on the old NPL Gold Key diskette. Then provide the serial number and reset count displayed by this program to Niakwa (Sales Order Desk), and they can give you a RESET code that the customer can enter when running the RESET program. This will re-establish installable security on the old Gold Key diskette, thus allowing you to run a Universal Upgrade.

Can I run a Universal Upgrade under Windows 95?

No. The NPL Universal Upgrade must interact with NPL RunTimes, which use an older version of security than  NPL Revision 4.2x and 4.3/5.0 RunTimes. This is one of the reasons that versions of NPL prior to 4.2x are not supported under Windows 95 and Windows NT. For this reason, the Universal Upgrade must be run on systems that can reliably execute the old NPL security. (NOTE: Shutting down Windows 95 to MS-DOS is a sufficient alternative.)

After upgrading, I get a message indicating a NIAKNETW mismatch. What does this mean?

This error can occur if you have updated the NPL Windows files on your system, but have not updated each workstation to use the current version of NIAKNETW.DLL. Be sure to remove all older versions of NIAKNETW.DLL from your system, and the message should go away.

Under Windows 95, I have defined my print devices to use the Windows Print Manager. The printer I select is directed to a print queue on the customer's network. When the customer prints in my application, everything seems like it prints fine, but the output is lost. What could be happening here?

This problem is related to the default settings in the Setup of a printer under Windows 95. To correct this, perform the following steps:

  1. From the Windows menu bar, click on Start, Settings, and Printers.
  2. Right click on the printer in question and select properties.
  3. Click the Details tab.
  4. Choose Spool Settings
  5. Verify that "Spool data format" is set to "RAW"

By default, Windows 95 will set the "Spool data format" to "EMF", thus causing the problem with no output.
