If you’re getting this error:

❌ Could not obtain a license for SolidWorks Standard. License error: -8,544,0

Don’t worry — this issue is very common and usually caused by a license server problem, firewall, or SolidNetWork License Manager not working properly.

Let’s go step-by-step to fix it 🔧

🔍 What Does Error (-8,544,0) Mean?

This error typically means:

• Your computer can’t connect to the license server
• Or the license service is not running
• Or the firewall/antivirus is blocking communication

✅ Step-by-Step Fix

🔁 1. Restart the SolidNetWork License Manager (SNL)

If you’re using a network license:

1. Press Windows + R
   Type: CopyEditservices.msc
2. Find SolidWorks FlexNet License Manager (or similar)
3. Right-click → Restart

Then try launching SolidWorks again.

📡 2. Check Server Connection (for Network Licenses)

Make sure your client machine can ping the license server.

• Press Windows + R, type: cmd
• Type: nginxCopyEditping YourLicenseServerName

If it doesn’t respond, it’s a network issue. Contact your admin or check LAN/Wi-Fi settings.

🔥 3. Allow SolidWorks Through Firewall

1. Open Windows Security > Firewall & Network Protection
2. Click Allow an app through firewall
3. Ensure these are allowed:
   • sw_d.exe
   • lmgrd.exe
   • swlicserv.exe

✅ Also allow TCP ports 25734 and 25735

💽 4. Re-Activate the License Manager (on Server)

If you’re the admin or using a local setup:

1. Go to SolidNetWork License Manager > Server Admin
2. Click Modify → choose Activate/Reactivate
3. Follow the wizard & re-activate your license

Then restart the license manager service.

🔌 5. Try Client-side Workaround

If you’re using SolidWorks on a standalone license, but still seeing this error:

1. Go to: makefileCopyEditC:\ProgramData\FLEXnet
2. Delete all files starting with SW_D or SW_D_...
   (This resets the license cache)
3. Relaunch SolidWorks — it will re-request the license.

🧯 Still Getting Errors?

You may need to:

• Reinstall SolidWorks License Manager
• Re-activate your serial key
• Check for corrupted FLEXnet services
