This error can occur if prior license information is still available on your system, or if the installation is performed with a prior version serial number.
Try the following to troubleshoot:
- Rename the FLEXnet folder and try the activation again:
Go to C:\ProgramData\FLEXnet and rename the folder FLEXnet (may be to FLEXnet_old) (The ProgramData folder is a hidden folder. Either you can enable to show hidden folders from Folder options, or you can directly type c:\Programdata into the address bar and press enter to access this folder. You will be able to find the Flexnet folder.)
- Try to activate again and if the error still occurs, confirm that a valid serial number is used for the SOLIDWORKS installation by modifying the installation. If the serial number is not a valid one, please change and input the correct serial number:
- Go to Start > Control Panel >SOLIDWORKS
- click ‘Change’ to modify the installation. Select ‘Modify the individual installation (on this computer)’ >click ‘Next’
- Under ‘serial number’ make sure that your valid serial number is in use
- If not, replace the serial number with a valid one and click ‘Next’
- Follow the instructions to complete the modification
- Rename the FLEXnet folder and try to activate again
If the problem still occurs, try doing a repair installation of SOLIDWORKS by following the steps below:

- Go to Start > Control Panel >SOLIDWORKS and click ‘Change’ to repair the installation
- Select ‘Repair the individual installation (on this computer)’
- Click ‘Next’. Follow the instruction to complete the modification
