I get an error when trying to run FIR Creator or FIR Designer on macOS

If you see the dialog “FIR Designer” can’t be opened because it is from an unidentified developer”, here’s what you should do:

  1. Click “ok” to close the “…can’t be opened…” dialog.
  2. Open “System Preferences” “Security & Privacy.”
  3. Unlock the security preferences by clicking the lock symbol next to “Click the lock to make changes.” (You will be prompted to enter your maxOS username and password.)
  4. Under “Allow apps downloaded from:”, note which checkbox is set, then check “Anywhere.”
  5. Click “Open Anyway.”
  6. If FIR Designer opens, close it.
  7. Under “Allow apps downloaded from:”, check the previous checkbox noted in 3.
  8. Click the lock symbol to lock the security preferences.
  9. Try running “FIR Designer” from the Applications folder. If the “…can’t be opened…” dialog appears again, close it, then go to “System Preferences” “Security & Privacy” and, once again, click “Open Anyway.”

From now on, FIR Designer will open without any warnings.

Can updates be installed over previous installs?

On Windows, you can either install an update over the existing install, or install to a unique directory. The installer wizard will prompt you to choose an install direction. If either install has been activated with a license key, both will work and both use the same “license.”

On macOS, if you drag-and-drop the newer “FIR Creator” or “FIR Designer” onto the “Applications” folder, you will be prompted to choose whether you want to “replacing” the existing version. To keep multiple versions, before installing the update, rename the existing “FIR Creator” or “FIR Designer” install that is in the “Applications” folder.

What are the purchase and licensing options?

Both FIR Creator and FIR Designer are available as a single-user license only. There are no discounts for businesses who purchase multiple licenses. Each license enables the user to install the application on ONE Mac or Windows device. It can be moved to a new Mac or Window device as needed, but multiple devices cannot simultaneously have the app activated using the same license ID and password. For example, if a business has three devices on which the app needs to be installed, three licenses must be purchased.

How does the license ID and activation work?

You will receive a license ID & password immediately upon payment.

An internet connection is required to activate FIR Creator or FIR Designer. In the “Help” menu, select “License,” enter the License ID and password, and press “Activate.”

Can I move a license from one computer to another?

Yes. To move a license to another computer, ensure the licensed computer is connected to the internet. In the “Help” menu, select “License” and press “Deactivate.” Then on the second computer, activate as normal.

What about licensing and virtual machines?

FIR Creator and FIR Designer cannot be activated in a virtual machine (VM).

Is an internet connection required to use FIR Creator or FIR Designer?

No; both products are fully functional both online and offline once activated. (An internet connection is required for activation).


they need to be run while connected to the internet every ~ 3 months. If you’re using either app offline and it’s just past three months since the last validation, a warning message will be displayed for the next ~1 month, requesting a restart of the app while connected to the internet. If this doesn’t occur, the product will drop back to demo mode (ie. project file saving & filter export will be disabled), EVEN IF your subscription payment is current (in the case of FIR Designer).

To re-enable full functionality, restart the product while connected to the internet.

How do I renew my FIR Designer 2 subscription?

You will receive a notification when the annual subscription payment is due. The notification will include the due date and instructions. If payment is not received, FIR Designer will drop back to demo mode (ie. project file saving & filter export will be disabled).
