How to force TaxCalc to re-license.

In certain scenarios it may be necessary for TaxCalc to be licensed under different accounts. 

This could occur if a user consults for multiple firms but also requires a personal licence to complete their own Self Assessment.

This article provides two methods of removing the licence key after which TaxCalc will need to be re-licensed. These methods are only suitable for Windows PCs. If you need to change the licence details on a mac, please see the link to our article for How to reset the licence details on a Mac

Before running the batch file please ensure that TaxCalc is closed.

Option 1 : Automatic deletion of TaxCalc licence key.

  1. Download the Licence_Keys_Remover zip file.
  2. Double click on the zip folder and extract the file.
  3. Run the Licence_Keys_Remover.bat file

Option 2 : Manual Edit of the Registry

Please note it is advisable to use the batch file in Option 1 to amend the registry. Please only attempt if you are confident to do so.

  1. Click on your Windows logo ()  type Regedit and open the Registry Editor.
  2. Navigate to HKEY_CURRENT_USER\SOFTWARE\Acorah Software Products\TaxCalcHub\APF\Discovery.
  3. Right click the ServerResponse key and select delete.
  4. Right click the ServerMac key if present and select delete.
  5. Browse to the Network folder
