This error can only occur if the wrong version of the Avalara.AvaTax.Adapter.dll is currently registered.

For Control version 4.5.1008.3001 and later, make sure Avalara.AvaTax.Adaptor.dll version is registered.

For all previous versions, make sure Avalara.AvaTax.Adaptor.dll version is registered.

Note: Right-click on the Avalara.AvaTax.Adaptor.dll and click on Properties, click on the Version tab to verify the version number.

Follow steps below to correct:

  1. If Avalara has been registered using the steps outlined here setting_up_online_taxes_avalara and the Ping Avalara in Control still generates an error stating the interface is not supported or cannot be found, check to see if the Avalara On-Demand Demo program is installed. If it's installed, uninstall it.
  2. Unregister the Avalara.AvaTax.Adaptor.dllfrom the SSLIP folder:
    1. Avalara.AvaTax.Adaptor.dll version

**//C:\Windows\Microsoft.Net\Framework\v2.0.50727\regasm.exe "C:\Program Files\Cyrious\SSLIP\Avalara.AvaTax.Adapter.dll /unregister"//**

  1. Avalara.AvaTax.Adaptor.dll version

**//C:\Windows\Microsoft.Net\Framework\v1.1.4322\regasm.exe "C:\Program Files\Cyrious\SSLIP\Avalara.AvaTax.Adapter.dll /unregister"//**

  1. Open the Registry Editor (regedit) and search the entire registry for the word Avalara and delete all entries. There are quite a few so this will take a few minutes, if you skip this step the error is still likely to occur.
  2. Shut down the SSLIP if running.
  3. Re-register the Avalara.AvaTax.Adaptor.dll for the appropriate version of Control. (4.5.1008.3001 and later uses version, earlier versions use

If you are able to ping Avalara but still receive this message you may be running out of drive space on the server (you will usually see an error message when starting the SSLIP as well)

  1. Check the amount of free space on the server (especially the C: drive)
  2. If there is no free space or very little free space, delete temp files or remove unwanted files that could be taking up needed space
  3. Restart the SSLIP
