Changing Your F/X CAD License Type


You need to change your F/X CAD license type after installing.


For example, when installing F/X CAD, you may have mistakenly selected the Trial option on the screen where you select your license type, and you now see a mostly empty white box in the middle of the screen on startup, with the text appearing so far off the screen that you can't read or click anything. Changing your license type will get rid of this white box.


You may also have received a FlexNet License Finder error upon opening CAD.

If you're missing the activation splash screen on startup and need to activate F/X CAD, these steps will allow you to re-enter your product information and open the activation screen.




Your solution will depend on your version of F/X CAD.




1. Open the Start menu.



2. Type CMD in the text field.



3. Select the Command Prompt entry.


The Windows Command line will open.




4. Copy and paste the following text at the command prompt:

cd %CommonProgramFiles(x86)%\Autodesk Shared\AdskLicensing\Current\helper\


Then press Enter.




5. Copy the following text, and paste it at the Command prompt:

AdskLicensingInstHelper change -pk 001L1 -pv 2020.0.0.F -lm ""


Then press Enter.

If you choose to type this command manually, note that the phrase -lm includes a lowercase L – not the number 1.


You should now be able to use F/X CAD without issue.

C:\CommonProgramFiles(x86)\Autodesk Shared\AdskLicensing\Current\helper\>AdskLicensingInstHelper change -pk 001L1 -pv 2020.0.0.F -lm ""


Getting feature failed: Get dial tcp connected: No connection could be made because the target machine actively refused it.



Did you see this error at this point? If so, follow our instructions to address the error. Then try Step 5 again.

Press Enter to navigate to the pasted folder location, then delete the file LoginState.xml.

6. Navigate to the location C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing.


Right-click the file uninstall.exe, then select Run As Administrator from the menu that opens.

If you see an Unknown Error message at this point, ensure that the following items are closed:

8. Ensure that the account LOCAL SERVICE has Full Control permission over the following folders:

Need help changing these files' permissions? See our instructions for changing file or folder permissions.

If these folders are missing, move on to the next step.




9. Restart your computer.




10. Follow our steps to temporarily disable User Account Control (UAC) in Windows. Also disable any antivirus software you have installed on your computer.




11. Download and install the latest Autodesk Licensing Service Update using the link below.

13. Reinstall F/X CAD 2020.

Still seeing an error message at this point?

Add exceptions to any antivirus or protection software for the two programs listed below.


• C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\



• C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\

2. The About dialog box will open.



Click the Manage License button.




3. The License Manager will open. Click Change License Type.

5. FX CAD will now ask you to either Save drawings and quit, or Quit without saving.



Select the option of your choice, depending on whether you need to save your drawing.



F/X CAD will close.




6. Start F/X CAD again. You'll now see the Let's Get Started screen, pictured below. Click Enter a Serial Number. You can then enter the Serial Number and Product Key for your installation of F/X CAD.



You or your office will have received an F/X CAD Serial Number and Product Key in an email from Land F/X. 


You should now be able to use F/X CAD without issue.
