Hardware fingerprint, product license, and adding RAM to a Laserfiche server.

Licensing Laserfiche
Updated April 1, 2015
asked on March 30, 2015

Hi all,

Adding RAM to a customer's Laserfiche server "broke" the licensing.  On startup, we saw eventID 10044 from LFS regarding the inability to find a valid product license.  Went back to 2(!) gigs of RAM and all is well.  

Is this normal?  How do we get up to 4GB and keep LFS happy?

Thanks

RM

This is somewhat expected, as licenses are tied to a specific machine by a hardware fingerprint (HWFP), so changes to the hardware would affect the HWFP. However, I believe just adding more RAM should usually be OK, as the algorithm used was intended to allow minor changes, so it's a bit surprising that you encountered the issue. Is it possible that other hardware changes were made since you installed the license? There is a limited number of changes that can be made without causing issues.

To resolve the problem, you would need to regenerate your license with the new fingerprint. The process is different for Rio (using License Manager or Directory SErver) and for Avante (or other licensing that does not use Directory Server or License Manager).

Using Directory Server/License Manager:

  1. Remove the existing application instance
  2. Create a new application instance with all the same resources (e.g., same number of named users and public portals), making sure that you retrieve the new hardware fingerprint, not just copy+paste the old one.
  3. Download a new license from the new application instance
  4. Replace the file lf.licx on the Laserfiche Server. By default, this file is under C:\Program Files\Laserfiche\Server
  5. Restart the Laserfiche Server service (either by using the Windows "Services" console or using Laserfiche Administration console)

 

If you are using Avante or other licensing types that do not use License Manager/Directory Server:

  1. With the machine in the old configuration (the one that works with the current license), run the showhwfp application found in the Server program files (by default, C:\Program Files\Laserfiche\Server )
  2. Copy the Hardware Fingerprint; you'll need this shortly. NOTE: if you are on Server 8.1, you must use the Legacy Hardware Fingerprint instead)
  3. Deactivate the license using ActivationTool.exe found in the same folder according to the direction in the KB article on deactivation, using the old hardware fingerprint you found earlier.
  4. Install the new hardware
  5. Determine the new hardware fingerprint
  6. Reactivate the license using ActivationTool.exe and the new hardware fingerprint. To activate instead of deactivate, simply leave off the -deactivate parameter
  7. Replace the file lf.licx on the Laserfiche Server with the new license generated by the activation tool. The license should be placed in the installation directory for the server, which is under C:\Program Files\Laserfiche\Server by default.
  8. Restart the Laserfiche Server service (either by using the Windows "Services" console or using Laserfiche Administration console)

Thanks for the excellent information.  I'll ask the dumb question now: How do I determine exactly which product this customer has?  The console indicates "Laserfiche group server" and "Laserfiche content repository server" with a license type of "Laserfiche classic."  I don't see anything that looks like a separate license server on the machine.

As for prior changes, I'm new to this environment so I don't know the history.  =(

The Admin Console would say "Laserfiche Rio" or "Laserfiche Avante". You're using the legacy licensing model, aka "Laserfiche Classic". The same steps Brianna outlined above for Avante apply to you too.

Does the deactivation and reactivation process require internet access?

Also, if we perform this procedure after hours and have trouble with reactivation, is the Laserfiche support organization available on nights and weekends?

The deactivation and reactivation process do require internet access, but it is possible to note the correct HWFPs for your server, perform the activation actions using the activation tool on a separate machine, then move the license generated by the tool to your server machine.

Yes it is must Internet Access for Activation & Deactivation
