"Unable to register resource file" error when updating TaxCalc

Article ID: 2984
Last updated: 07 Feb, 2020

Some users have reported the below error message when attempting to update TaxCalc.

Please note this error should only affect Windows users. If you are running a different operating system, please contact our support team for further assistance.

This means that there has been an error in updating the plugins which are needed to run TaxCalc. To resolve this please attempt the below steps:

  1. Click on the windows logo in the bottom left and start typing '%LocalAppdata%
  2. Open the Acorah Software Products > TaxCalcHub folder.
  3. Rename the Plugins folder to pluginsold or any other derivative.
  4. Restart TaxCalc.

The required files should now be downloaded from our website and TaxCalc should open as required.

If this does not work and you are presented with the same error, you will need to open the same folder as above and see if a new plugins folder has appeared. If not, the only way to retrieve this information is by re-running the installer file from our website. You should:

  1. Log in to the TaxCalc website with your credentials
  2. Click on My Account > My Products and Services
  3. Click on Download

We would always recommend saving the installer file and running the file as administrator.
