Trouble installing or running?

If you have downloaded nXt but are having difficulty, it may be necessary to change some settings in order to run it. Below are known issues and solutions:

Macros disabled by default

Microsoft have added security checks to Windows, which disable macros by default in workbooks that have been downloaded from the internet. They call this “Mark of the Web”.

If you encounter this, you can manually enable macros in nXt as follows:

  1. Navigate to the file location for the nXt add-in. If you used the installer, this is the location:
  2. C:\Users\[Your user name]\AppData\Roaming\Numeritas\nXt_lite
  3. Right click on the file nXt (it may be displayed as nXt.xlam depending on your settings) and select properties.
  4. In the Properties dialog box on the General tab, you will see a security section at the bottom. Check the Unblock checkbox.
  5. Click OK

You should now be able to run nXt normally.
