SOLIDWORKS Error: Failed to Obtain Computer Identifier

Article by Rodolfo Gutierrez on Jul 02, 2021

When booting SOLIDWORKS, are you getting the error, "Failed to obtain computer identifier"? This message is coming from SOLIDWORKS’ licensing system, FlexNet. The first time you activate SOLIDWORKS, regardless of the license type (standalone or network), the FlexNet licensing service generates a unique and proprietary computer ID to identify your computer.

Every time you start SOLIDWORKS, most of the activation process comprises verifying this computer ID. If the computer ID cannot be verified, SOLIDWORKS will throw out this error message: “Failed to obtain a computer identifier. You can continue, but you might have activation or transfer issues in the future. Please contact your reseller for support.”

This could mean the FlexNet licensing server service is not running, there have been recent updates to your operating system, or there may be faulty or missing computer hardware.

In this article, we'll walk through these four solutions:

  1. Ensure the FlexNet license service is running
  2. Repair SOLIDWORKS
  3. Check for missing or faulty hardware
  4. Find the computer ID on an activated computer

Let's get started.

Ensure the FlexNet license service is running

Go to Control Panel > System and Security > Administrative Tools > Services OR Type ‘Services’ in the Windows Start menu.

Find the FlexNet Licensing Service and FlexNet Licensing Service 64 services and ensure they are both running. (Figure 1)

If you have had updates to the operating systems and are getting this error message, please run a SOLIDWORKS repair installation. 

To do so, please follow this guide: SOLIDWORKS Installation Repair

Check for missing or faulty hardware

The FlexNet licensing service uses a combination of computer hardware, such as hard drives, network cards, along with other system components to create each unique computer ID. If one of those components is missing, faulty, or there is an issue with a driver, the activation system cannot obtain the computer identifier. 

Open system information by hitting Windows+R and opening the Run box. Type ‘msinfo32’ > Open. (Figure 2)
