Occasionally, on a fresh install of one of the many CData Excel Add-ins, you will see the below error:

 ![99430fce-6b55-4938-8adc-3353edef4b87.png](https://us1.discourse-cdn.com/cdata/original/2X/d/dc25f762f8c56ce69d70cc63fbe4eb00f79d319b.png)

This error means that either a system IT policy, or antivirus software has blocked a portion of the Excel Add-in from functioning, and the Add-in will be unable to do key processes such as launching the OAuth flow.

The fix is simple, but will require a System or IT Administrator who can make changes to the IT or Antivirus policy. To allow the Add-In to function, you will need to ensure that CMD.EXE, specifically at either the path C:\Windows\System32\cmd.exe or the path&nbsp; C:/Windows/SysWOW64/cmd.exe, is removed from the list of threats and not blocked by antivirus software and the firewall.
